摘要

We investigate how to give new representations of (b, c)-inverses in terms of core inverses and Drazin inverses. Various new criteria and representations of (b, c)-inverses in terms of core inverses and Drazin inverses are established from a new perspective. Since Moore-Penrose inverses, pseudo-inverses, core inverses, dual core inverses, and Bott-Duffin (e, f)-inverses are the special cases of (b, c)-inverses, new characterizations involving these generalized inverses are also established as corollaries of our results.
