*The quadratic forms in three variables over the field are classified. Some remarks are made about the group of equivalences of the quadratic forms. By a quadratic form, we understand a homogeneous quadratic polynomial in variables where the belong to a field or at least a commutative ring.*

The main purpose of this research project is to use a multidisciplinary approach to attack some important open problems in Algebraic Geometry, Arithmetic Geometry , Quadratic Forms and Algebraic Groups Algebraic geometry and the Theory of Motives - generalization of the Suslin-Gabber rigidity theorems. Number of points over a finite field - Applications of the classification of formal groups and finite group schemes to good and semistable reduction of Abelian varieties in order to find explicit formulas for generalized Hilbert symbols over formal group modules over ramified multi-dimensional local field - Construction of the affine Grassmanian for two-dimensional local field in order to find a connection between the Krichever correspondence for algebraic surfaces and the higher KP-systems Quadratic forms The research will develop along the lines of the results recently obtained by Vishik, Voevodsky, Karpenko and Rost on the classification of anisotropic quadratic forms. The structire of the Chow motive of a quadric will be further studied and the Vishik character. Bott periodicity in hermitian K-theory for any ring and its relation with the classification of quadratic forms. Linear algebraic groups The aim is to prove Rosenberger's Conjecture on the Tits alternative for generalized triangle groups; Also the theory of sums of orbits of algebraic groups will be developed in order to prove an analogue of Deligne-Simpson problem.

## Quadratic form

Quadratic form. A quadratic form is a homogeneous polynomial of degree two. The following are quadratic forms in one, two and three variables:. The polynomial consists of squared terms for each of the variables plus cross-products terms for all combinations of the variables. Quadratic forms occur in many branches of mathematics and its applications. They are encountered in the theory of numbers, in crystallography, in the study of surfaces in analytic geometry, and in various problems of physics and mechanics.

In mathematics , a quadratic form is a polynomial with terms all of degree two " form " is another name for a homogeneous polynomial. For example,. The coefficients usually belong to a fixed field K , such as the real or complex numbers, and one speaks of a quadratic form over K. Quadratic forms occupy a central place in various branches of mathematics, including number theory , linear algebra , group theory orthogonal group , differential geometry Riemannian metric , second fundamental form , differential topology intersection forms of four-manifolds , and Lie theory the Killing form. Quadratic forms are not to be confused with a quadratic equation , which has only one variable and includes terms of degree two or less. A quadratic form is one case of the more general concept of homogeneous polynomials.

Quadratic Forms and Matrices: An Introductory Approach focuses on the principles, processes, methodologies, and approaches involved in the study of quadratic forms and matrices. The publication first offers information on the general theory of quadratic curves, including reduction to canonical form of the general equation of a quadratic curve, invariants and classification, reduction to canonical form of the equation of a quadratic curve with center at the origin, and transformation of coordinates in the plane. The text then examines the general theory of quadratic surfaces. Topics include transformation of rectangular coordinates in space; general deductions based on the formulas for the transformation of coordinates; reduction to canonical form of the equation of a quadric with center at the origin; and reduction to canonical form of the general equation of a quadric surface. The manuscript ponders on linear transformations and matrices, including reduction of a quadratic form to canonical form; reduction to canonical form of the matrix of a symmetric linear transformation of space; change of the matrix of a linear transformation due to a change of basis; and geometric meaning of the determinant of a linear transformation. The publication is a vital reference for researchers interested in the study of quadratic forms and matrices.

### Algebraic cycles, quadratic forms and motives

Пожалуй, я все же оставлю ей записку. - И он положил конверт на стойку. Консьерж взглянул на конверт и что-то грустно пробормотал себе под нос. Еще один любитель молоденьких девочек, - подумал .

Сьюзан подбежала к. - Коммандер. Стратмор даже не пошевелился.

Ком… мандер, - задыхаясь, пробормотала она, сбитая с толку. - Я думала… я думала, что вы наверху… я слышала… - Успокойся, - прошептал. - Ты слышала, как я швырнул на верхнюю площадку свои ботинки. Сьюзан вдруг поняла, что смеется и плачет одновременно. Коммандер спас ей жизнь.

Клушар кивнул: - Со спутницей.
