In this paper, we consider the positive semidefinite solution of the matrix equation (AT X A, BT X B) - (C, D). A necessary and sufficient condition for the existence of such solution is derived using the generalized ...

The purpose of this paper is to study the following two questions on AP-injective rings: (1) R is a regular ring if and only if R is a left PP-ring and R is left AP-injective; (2) Let R be a right .AP-injective ring. ...

The purpose of this paper is to characterize strongly regular rings via MERT rings and weakly one-sided ideals. Many important equivalent conditions on strongly regular rings are shown.
This paper, as a natural sequel to [1], gives the further consideration of problem I posed by Liao Anping and Guo Zhong in [2]: given X, Z ∈ Rn×m, Y, W ∈ Rn×l, find A ∈ R0n×n such that AX = Z, yTA = WT, where R0...
