Generalized inverses and Douglas equations

M. Laura Arias; Gustavo Corach; M. Celeste Gonzalez

In this paper we study the general concept of reduced solution for a Douglas type equation and we parametrize these solutions using generalized inverses. On the other hand, we characterize different sorts of generalized inverses by means of solutions of Douglas type equations.
