Random matrix theory (RMT) has emerged as a powerful framework for analysing complex systems across physics, statistics and beyond, by examining the statistical properties of matrices with random ...

We determine the general solution of the functional equation $f(x + y) + f(x - y) = A(y)f(x)\quad (x, y \in G),$ where G is a 2-divisible abelian group, f is a vector ...

The present paper is concerned with the solution of the coupled generalized Sylvester-transpose matrix equations { A 1 X B 1 + C 1 X D 1 + E 1 X T F 1 = M 1 , A 2 X B 2 + C 2 X D 2 + E 2 X T F 2 = M 2 ...
