If f a cadeau noel dora x 2 b x y c y 2 displaystyle fax2bxycy2, then important invariants include The discriminant b 2 4.
The most general method is Venkov's method.Over a organiser un jeu concours en entreprise commutative ring with an identity, a homogeneous polynomial in variables with coefficients.Let be the set of matrices over of positive -ary quadratic forms satisfying the equation.Composition means taking 2 quadratic forms of the same discriminant and combining them to create a quadratic form of the same discriminant, it is a generalization of the 2-square identity ( a 2 b 2 ) ( c 2 d 2 ) (.In the field ( ) the problem of equivalence is solved by means of the Hasse invariant.Another way of looking at quadratic forms is the following.On the basis of this algorithm a precise fundamental domain is constructed for.The form is called reducible if is non-empty.The prime examples are the solution of Pell's equation and the representation of integers as sums of two squares.We obtain more pairs that work by switching the values of x displaystyle x and y displaystyle y and/or by changing the sign of one or both of x displaystyle x and y displaystyle.Equivalent quadratic forms represent the same elements.385401 MR08707.10017.If two integral quadratic forms and are equivalent, then there exists an integral transformation, the absolute values of the elements of which are bounded by a constant depending only on and, that takes.
