Abstract
Let A be a square complex matrix. Let PP be one of the following properties: (a) A is an EP matrix, (b) the column space of A is complementary to the column space of A∗A∗, and (c) the orthogonal complement of the column space of A is the column space of A∗A∗. We study the canonical angles between the column space of A and the column space of A∗A∗ when A satisfies property PP. Also, we research the following problem: Let {Am}m=1∞ be a sequence of matrices satisfying property PP that converges to some matrix A. When does A satisfy property PP?
