Some remarks on generalizations of the reverse order law in a *-ring

MATHEMATICA
The authors show that under a suitable condition certain reverse order laws are equivalent. Furthermore, by investigating a reverse order law in rings with involution, they show that under suitable assumptions a certain inclusion is always an equality.

REVERSE AND FORWARD ORDER LAWS OF CERTAIN INVERSES

Journal of Mathematical Analysis
Reverse and forward order laws for closed range operators such as idempotent operators, normal operators, regular operators on the Hilbert spaces are studied. Basically, these laws are established for core inverse, Moore Penrose inverse and group inverse under certain necessary and sufficient conditions noticing the entries of matrix representations of

Reverse-Order Law for Weak Core Inverse

ICCK Journal of Applied Mathematics
In this paper, some sufficient conditions for the reverse-order law of the weak core inverse are obtained. Several characterizations of the reverse-order law for this generalized inverse are then established. In addition, some results concerning the absorption law for the weak core inverse are proved.
