Abstract


In this
paper, we consider Moore-Penrose invertible, group invertible, and
core invertible elements in rings with involution to characterize
EP, generalized normal, generalized Hermitian elements and
generalized partial isometries. As a consequence, we obtain new
characterizations for elements in rings with involution to be
normal and Hermitian elements.
