| Popis: | We introduce the class of quasi-2-isometric operators on Hilbert space. This class extends the classes of 2-isometric operators due to Agler and Stankus and quasi-isometries by S.M.Patel. An operator T on a complex Hilbert space is called quasi-2-isometry if In the present article, we give operator matrix representation of quasi-2-isometric operator in order to obtain spectral properties of this operator. |
