报告摘要
In this talk, we talk about the generalized inverses of linear combinations of two generalized invertible elements. (1) We give the existence criterion and formulae of Drazin inverses of elements in a certain finite-dimensional algebra generated by two idempotents, under some prescribed conditions. (2) In Dedekind-finite ring, we present the group inverse of sum of two group invertible elements under different conditions. Then, the core inverse of a sum of two core invertible elements is investigated. Furthermore, the core inverse of the difference of two core invertible elements is presented. These results generalized the corresponding results of complex matrices. (3) We present the core inverses of linear combinations of two core invertible complex matrices. Furthermore, sufficient conditions, which guarantee that the difference of two core invertible matrices is core invertible, are presented.
