Centralizer's applications to the (b, c)-inverses in rings
[EN] We give several conditions in order that the absorption law for one sided (b,c)-inverses in rings holds. Also, by using centralizers, we obtain the absorption law for the (b,c)-inverse and the reverse order law of the (b,c)-inverse in rings. As applications, we obtain the related results for the inverse along an element, Moore-Penrose inverse, Drazin inverse, group inverse and core inverse.This research is supported by the National Natural Science Foundation of China (no. 11771076 and no. 11871301).

Characterization and Representation of Weighted Core Inverse of Matrices
In this paper, we introduce new representation and characterization of the
weighted core inverse of matrices. Several properties of these inverses and
their interconnections with other generalized inverses are explored. Through
one-sided core and dual-core inverse, the existence of a generalized weighted
Moore-Penrose inverse of matrices is proposed. Further, by applying a new
representation and using the properties of the weighted core inverse of a
matrix, we discuss a few new results related to the reverse order law for these
inverses.Comment: 18 page
