A way to construct 2x2 real matrices whose squares are the negative of the identity
A way to construct 2x2 real matrices whose squares are the negative of the identity
AbstractA matrix whose entries are +, −, and 0 is called a sign pattern matrix. We first characteriz...
It is shown that a sufficient condition for a nonnegative real symmetric matrix to be completely pos...
AbstractNew matrices-minus-diagonal are constructed. This implies the existence of sets of 10 mutual...
A way to construct 2x2 real matrices whose squares are the negative of the identity; Landau's fourth...
In this article, the author investigates the real 2 x 2 matrices which admit real square roots
We know that square of a real number is always non-negative e.g. and . Therefore, square root of ...
Throughout, we work in the real polynomial ring in two variables, which we denote by R[x, y]. The se...
