Group inverses and Drazin inverses of matrices over rings

1992
Summary: We give necessary and sufficient conditions for a class of matrices to have a group inverse or Drazin inverse. Moreover, expressions for these inverses are obtained. This kind of matrix includes all matrices over a left and right principal ideal domain.
