Resumen:
This paper deals with the minus, star and sharp partial orders in the complex matrix setting. The main tool used in our work is the Hartwig-Spindelböck decomposition obtained in [Matrices for which $A*$ and $A+$ commute, Linear and Multilinear Algebra 14 (1984), 241--256]. Weexploit this decomposition to characterize the form of the predecessors of a fixed element under the three mentioned partial orders.
