»ã±¨ÌáÒª£ºIn 2011, Mary introduced the notion of inverse along an element, he proved the Moore-Penrose inverse, Drazin inverse and group inverse are some kind of the inverses along to an element. In 2012, Drazin introduced the notion of (b, c)-inverse, we call it the inverse along two elements. In particular, the inverse along an element d is same as (d, d)-inverse. In this talk, we give some progress on the inverses along an element and (b, c)-inverses. Many results unify the results of Moore-Penrose inverses, Drazin inverses, group inverses and inverses along an element, respectively.
