On (N,M)-a-normal And (N, M)-a-quasinormal Semi- Hilbert Space Operators

Samir Al Mohammady, Sid Ahmed Ould Beinane, Sid Ahmed O. Ahmed Mahmoud

The purpose of the paper is to introduce and study a new class of operators on semi-Hilbertian spaces i.e.; spaces generated by positive semidefinite sesquilinear forms. Let H be a…
