两个幂等算子多线性组合的 Drazin 逆
On the Drazin Inverses of Multiplicative Combinations Associated with Two Idempotents
摘要
Abstract
By using the block-operator matrix technique and the decomposition of the infinite dimensional complex Hilbert spaces, the representations of the Drazin inverses of multiplicative combinations associated with two idempotents P,Q on a complex Hilbert space were obtained under the conditions PQP =P, PQP =0, PQP =PQ.关键词
