The sum of involutory matrices
Let K be a commutative ring with unity. An n-by-n matrix A, with entries in K,is said to be an involution if A2 = In. If A2= -In, we say that A is a skew-involution. For K=C,R,Q,Z and Zk, this paper determines the necessary and sufficient conditions for an n-by-n matrix to be expressible as a sum of...
