Gupta said mathematics had been her favourite subject since childhood. She said her senior introduced her to the BSc Maths Hons course, adding that she was elated to be able to learn and solve maths problems. The mathematician went on to add that while her parents wanted her to get a decent degree and then get married, they motivated her to continue her academic pursuits once they realised her interest.

She also hailed her mother for supporting her. Speaking to IE Online about the notion that boys were better at calculative subjects than girls, Gupta said the trend was now changing. She said she was the only girl in her class during her postgraduation days. But now, as a professor, she sees more women pursuing mathematics. Gupta attributed it to higher awareness among the youth and their parents, who now afford greater opportunities to their daughters to follow their interests.

Gupta is the third woman and fourth Indian to win the Ramanujan Prize, first awarded in Prior to her, three of the winners were associated with ISI, Kolkata. She said ISI Kolkata was a premier institute for those interested in pursuing higher studies in statistics and mathematics.

It is these repeating patterns that occupy buy and sell orders. This provides a diffusive economy both the financial investor and the financial systems modeler which underlies the Efficient Market Hypothesis EMH and alike and it is clear that although economies have undergone financial portfolio rationalization.

However, there is a and the parameter settings upon which the algorithm relies. Modern Portfolio series are characterized by long tail distributions which do Theory MPT is concerned with a trade-off between risk not conform to Gaussian statistics thereby making financial and return. Nearly all MPT assumes the existence of a risk- risk management models such as the Black-Scholes equation free investment, e.

Financial Derivatives information will dominate. As markets have grown and evolved, new trading contracts Unlike the EMH, the FMH states that information is have emerged which use various tricks to manipulate risk.

Derivatives are deals, the value of which is derived from Because the different investment horizons value information although not the same as some underlying asset or interest differently, the diffusion of information is uneven. Unlike rate. There are many kinds of derivatives traded on the most complex physical systems, the agents of an economy, markets today.

These special deals increase the number of and perhaps to some extent the economy itself, have an extra moves that players of the economy have available to ensure ingredient, an extra degree of complexity. This ingredient that the better players have more chance of winning. To is consciousness which is at the heart of all financial risk illustrate some of the implications of the introduction of management strategies and is, indirectly, a governing issue derivatives to the financial markets we consider the most with regard to the fractional dynamic model used to develop simple and common derivative, namely, the option.

In principle, this can be achieved for any financial date in the future and at an agreed price, called the strike time series, providing the algorithm has been finely tuned price. Alternatively, the investor might buy a call If a market maker can sell an option and hedge away all the option, the right to buy a share at a later date. If the asset is risk for the rest of the options life, then a risk free profit is worth more than the strike price on expiry, the holder will guaranteed. Options are usually sold by banks to at the higher price and generate an automatic profit from the companies to protect themselves against adverse movements difference.

The catch is that if the price is less, the holder in the underlying price, in the same way as holders do. If expect to make a profit by taking a view of the market. The agents taking the opposite puts. The principal question is how everyone thought it would rise. Thus, the psychology and much should one pay for an option?

But how do we quantify exactly how The risk associated with individual securities can be much this gamble is worth? However, they ought to have. The strike prices of these options were not all risk can be removed by diversification. The value of options rises in omy.

This remaining risk is generally referred to as loss is always limited to the cost of the premium. This gain market risk. Another role is Hedging. The investor would not want to liquidate holdings and time t denoted by V S, t. Here, V can denote a call only to buy them back again later, possibly at a higher price or a put; indeed, V can be the value of a whole portfolio or if the estimate of the share price is wrong, and certainly different options although for simplicity we can think of it having incurred some transaction costs on the deals.

If a as a simple call or put. The investor is paid for up front, is taken to satisfy the Black-Scholes can then immediately buy them back for less, in this way equation given by[3] generating a profit and long-term investment then resumes. As with other value of a put option rises when the underlying asset value partial differential equations, an equation of this form may falls, what happens to a portfolio containing both assets have many solutions.

The value of an option should be and puts? The answer depends on the ratio. There must unique; otherwise, again, arbitrage possibilities would arise. Take for in the portfolio. This ratio is instantaneously risk free. An Figure 1.

This is the most important of the shortcomings relating where to the EMH model i. This simple comparison indicates say that traders are not estimating the future price, but are a failure of the statistical independence assumption which guessing about how volatile the market may be in the future. However, Black-Scholes analysis cycles.

Non-periodic cycles correspond to trends that persist is ultimately based on random walk models that assume for irregular periods but with a degree of statistical regularity independent and Gaussian distributed price changes and is often associated with non-linear dynamical systems. The principal assumption associated with valuable if we can be sure that it truly reflects reality for RSRA is concerned with the self-affine or fractal nature which tests are required.

Ralph Elliott first reported on Gaussian distributed. However, it has long been known that the fractal properties of financial data in Hydrologists usually begin by assuming that the water influx is random, a perfectly reasonable assumption when dealing with a complex ecosystem.

Hurst, however, had studied the year record that the Egyptians had kept of the Nile river overflows, from to Hurst noticed that large overflows tended to be followed by large overflows until abruptly, the system would then change to low overflows, which also tended to be followed by low overflows.

There seemed to be cycles, but with no predictable period. Standard statistical analysis revealed no Figure 2.

These models can capture many results from the fact that increments are identically and properties of a financial time series but are not based on independently distributed random variables.

In short, his method was as follows: Begin with III. For markets it A time series is fractal if the data exhibits statistical self- might be the daily changes in the price of a stock index.

They also tend off at the expressed or implied, but the design to the accuracy, attractions, including South. So, you precompute. Add even further etwas unscharf und.Geometrically, affine transformations affinities preserve collinearity: so they transform parallel lines into parallel lines and preserve ratios of distances along parallel lines. We identify as affine theorems any geometric result that is invariant under the affine group in Felix Klein 's Erlangen programme this is its underlying group of symmetry transformations for affine geometry.

Consider in a vector space V , the general linear group GL V. It is not the whole affine group because we must allow also translations by vectors v in V. Here we think of V as a group under its operation of addition, and use the defining representation of GL V on V to define the semidirect product. For example, the theorem from the plane geometry of triangles about the concurrence of the lines joining each vertex to the midpoint of the opposite side at the centroid or barycenter depends on the notions of mid-point and centroid as affine invariants.

Other examples include the theorems of Ceva and Menelaus. Affine invariants can also assist calculations. For example, the lines that divide the area of a triangle into two equal halves form an envelope inside the triangle. Familiar formulas such as half the base times the height for the area of a triangle, or a third the base times the height for the volume of a pyramid, are likewise affine invariants.

Hence it holds for all pyramids, even slanting ones whose apex is not directly above the center of the base, and those with base a parallelogram instead of a square. The formula further generalizes to pyramids whose base can be dissected into parallelograms, including cones by allowing infinitely many parallelograms with due attention to convergence.

The same approach shows that a four-dimensional pyramid has 4D hypervolume one quarter the 3D volume of its parallelepiped base times the height, and so on for higher dimensions. Two types of affine transformation are used in kinematics , both classical and modern. Velocity v is described using length and direction, where length is presumed unbounded.

This variety of kinematics, styled as Galilean or Newtonian, uses coordinates of absolute space and time. The shear mapping of a plane with an axis for each represents coordinate change for an observer moving with velocity v in a resting frame of reference. Finite light speed, first noted by the delay in appearance of the moons of Jupiter, requires a modern kinematics.

The method involves rapidity instead of velocity, and substitutes squeeze mapping for the shear mapping used earlier. This affine geometry was developed synthetically in In , "the affine plane associated to the Lorentzian vector space L 2 " was described by Graciela Birman and Katsumi Nomizu in an article entitled "Trigonometry in Lorentzian geometry". Affine geometry can be viewed as the geometry of an affine space of a given dimension n , coordinatized over a field K. There is also in two dimensions a combinatorial generalization of coordinatized affine space, as developed in synthetic finite geometry.

In projective geometry, affine space means the complement of a hyperplane at infinity in a projective space. Synthetically, affine planes are 2-dimensional affine geometries defined in terms of the relations between points and lines or sometimes, in higher dimensions, hyperplanes.

Defining affine and projective geometries as configurations of points and lines or hyperplanes instead of using coordinates, one gets examples with no coordinate fields. A major property is that all such examples have dimension 2. Finite examples in dimension 2 finite affine planes have been valuable in the study of configurations in infinite affine spaces, in group theory , and in combinatorics.

Despite being less general than the configurational approach, the other approaches discussed have been very successful in illuminating the parts of geometry that are related to symmetry. In traditional geometry , affine geometry is considered to be a study between Euclidean geometry and projective geometry.

On the one hand, affine geometry is Euclidean geometry with congruence left out; on the other hand, affine geometry may be obtained from projective geometry by the designation of a particular line or plane to represent the points at infinity.

Affine geometry provides the basis for Euclidean structure when perpendicular lines are defined, or the basis for Minkowski geometry through the notion of hyperbolic orthogonality.

Peano , D. Hilbert , and O. Veblen who filled in the logical gaps left by Euclid in his Elements. The updates incorporate axioms of Order , Congruence , and Continuity. Euclid's half-intuitive, half-formalized Common Notions are directly included into the axiomatic system.

In the following, I shall nonetheless relate to the set of Postulates as they appear in Elements. Another approach to defining and classifying various geometries was introduced, in , by Felix Klein in the inaugural address he gave upon appointment to the Faculty and Senate of the University of Erlanger. The approach became known as the Erlanger Programm. To prove I. Superposition is achieved by transforming one triangle onto another. Euclid implicitly assumed that geometric figures do not change by rigid motions.

Rigid motions e. Put another way, in Euclid's geometry, some properties of figures lengths, angles, areas remain invariant under the group of rigid motions. As Klein showed, other although not all geometries can be characterized by various groups of transformations.

Since then, study of particular kinds of transformations became an integral part of geometric research and development. On this page, for the reference sake, I shall collect short Descriptions of and facts from various geometries as they become necessary for other discussions. In time, the page will serve as an index for more detailed coverage. The term Absolute Geometry had been introduced by J. Bolyai in Absolute Geometry is derived from the first four of Euclid's postulates.

Euclid apparently made a conscientious effort to see how far he can reach without invoking his Fifth postulate. All theorems of Absolute Geometry are automatically true in the geometries of Euclid, Lobachevsky and Riemann since those three only differ in their treatment of the Fifth postulate. For example Elements, I. If two straight lines cut one another, they make the vertical angles equal to one another. Affine Geometry is not concerned with the notions of circle , angle and distance.

It's a known dictum that in Affine Geometry all triangles are the same. In this context, the word affine was first used by Euler affinis. In modern parlance, Affine Geometry is a study of properties of geometric objects that remain invariant under affine transformations mappings.

Affine transformations preserve collinearity of points: if three points belong to the same straight line, their images under affine transformations also belong to the same line and, in addition, the middle point remains between the other two points. As further examples, under affine transformations. One way to arrive at the matrix representation is to select two points two origins and associate with each an appropriate number of independent vectors 2 in the plane, 3 in the space , to form an affine basis.

Each basis defines a system of coordinates. Point f x has the same coordinates in the second system as x has in the first. From here, it is just one step to the homogeneous coordinates which play an important role in Projective Geometry. Affine transformations can also be defined in terms of barycentric coordinates. Choose two arbitrary triangles and associate with each a system of barycentric coordinates.

Such an association of barycentric coordinates leads to an affine transformation under which vertices of one triangle correspond to vertices of the other which, in particular, explains the dictum at the beginning of this section. Pascal, G. Monge and was further developed in the 19th century by J. Poncelet and C. Brianchon Intuitively, Projective Geometry of a plane starts in a three dimensional space.

Points on that plane are associated with straight lines through point O. Incidentally, the set of all lines through a given point is called a pencil of lines. The set of all planes through a point is called a bundle of planes. Planes through O become straight lines in the projective plane. A fundamental fact about this correspondence is that the image of any other straight line parallel to AB will pass through the point P.

P is known as the vanishing point in the direction defined by AB. There is one caveat though. However, internally, elements of a pencil are indistinguishable. Only after the observation plane is selected, there appears one plane and the lines that belong to it that is discriminated against. By definition, Projective Plane is a pencil of straight lines and a bundle of planes through the same point.

When modeled with a projective mapping as above, the plane of the bundle parallel to the observation plane, is called the line at infinity. Each line in the pencil parallel to the observation plane defines a point at infinity.

In the point of view of Cartan connections, however, the affine subspaces of Euclidean space are model surfaces — they are the simplest surfaces in Euclidean 3-space, and are homogeneous under the affine group of the plane — and every smooth surface has a unique model surface tangent to it at each point. A choice of affine connection is also equivalent to a notion of parallel transportwhich is a method for transporting tangent vectors along curves. |
