Norm attaining and absolutely norm attaining of *-paranormal operators

Salah Mecheri

Abstract


Author in [10] gave a characterization for norm attaining and absolutely
norm attaining paranormal operators. In the present paper, we generalize
these results for -paranormal operators. We prove that elements of this
class of operators admit invariant subspaces as an extension of Istratescu result
[9]. Compacity and conditions for normality of norm attaning -paranormal
are also established.
