Survey on Reverse Order Laws for the Moore-Penrose Inverse of Hilbert Space Operators

Nebojša Č. Dinčić, Dragan S. Djordjević

This survey article contains results from seven original research papers published by the authors in past ten years on the topic of the reverse order laws for the Moore--Penrose inverse of the Hilbert space operators. Some proofs are improved, and there are some new results in the seventh section.
