摘要： Suppose A,B and C are the bounded linear operators on a Hilbert space H, when A has a generalized inverse A^- such that (AA^-)^*=AA^- and B has a generalized inverse B^- such that (B^-B)^*=B^-B,the general characteristic forms for the critical points of the map F_p:X^→‖AXB-C‖_p^p(1<p<∞), have been obtained, it is a generalization for P J Maher’s result about p=2. Similarly, the same question has been discussed for several operators.
