• Some Remarks on Generalized Inverses of Conjugate EP Matrix
AR. Meenakshi and R. Indira
Abstract. The existence of a group inverse and characterization of generalized inverses of a Con-EP (Conjugate EP) matrix are studied and it is shown that for a Con-EP matrix A, A is not a polynomial in A and group inverse does not coincides with A . Conditions are derived for AT to be a polynomial in A for a Con-EP matrix A.
