矩阵的两个幂等矩阵组合的可逆性
Invertibility of the combination of two idempotent matrices which products is idempotent matrix
摘要
Abstract
By using the nonsingularity of difference and sum of two idempotent matricesP、Q,we study the invertibility of the combination T =aP + bQ +cPQ +dQP +ePQP+fQPQ+g(PQ)2,(a,b,c,d,e,f,g ∈ C,ab≠0) under the condition of(PQ)2 =PQ.Furthermore,the expression of its inverse is provided in this paper.关键词
