There are two methods of reduction of positive definite quadratic forms due to Voronoi. One of these methods is based on the perfect forms and the other on the type of Voronoi polyhedra associated with the form. It was conjectured by Voronoi that these two methods are strongly connected. It...
basic positive definite quadratic form基本正定二次型 1.In this paper,We give concepts of positive definite matrix basis and orthogonal matrix basis,and show that every real quadric form can be lineally expressed by basic positive definite quadratic form; every linear transformation in Euclidean space...
an expression of the form(where aik = aki) that assumes nonnegative values for all real values of x1, x2,…, xn and that vanishes only when x1 = x2 = … = xn = 0. Thus, the positive definite quadratic form is a special case of a quadratic form. Any positive definite quadratic ...
1) positive definite quadratic form 正定二次型 1. A non-equality and its proof based onpositive definite quadratic form; 基于正定二次型的一个不等式及其证明 2. The paper is mainly about two opposite questions on quadratic form:one is the opposite question on its standard form,the other is ...
负定矩阵和半负定矩阵的定义类似。非半正定和非半负定(not positive semi-definite and not negative semi-definite)的矩阵有时称为不定(indefinite)矩阵。 等效条件 从上述定义可知,矩阵是正定的当且仅当它是正定二次型(positive-definite quadratic form)或 Hermitian 型矩阵。换句话说,矩阵是正定的当且仅当它...
curvesLet F(x, y) = ax2 + bxy + cy2 be a positive definite binary quadratic form with discriminant 螖 whose base points lie on the line x = -1/m for an integer m = 2, let p be a prime number and let Fp be a finite field. Let EF : y2 = ax3 + bx2 + cx be an ...
