Abstract:
In the present paper, taking some advantages oered by the con-text of nite dimensional Hilbert spaces, we shall give a complete characteriza-
tions of certain distinguished classes of operators (self-adjoint, unitary re ec-
tion, normal) in terms of operator inequalities. These results extend previous
characterizations obtained by the second author.
