New generalized results of (A,)-expansive operators on Hilbert spaces with practical comparison
In this research, we obtain some result related to a category of linear bounded operators, which is known as $(A, m)$-expansive operators acting on infinite dimentional Hilbert space. Moreover, we provide sufficient conditions which $(A, m)$-expansive operators are not supercyclic. We also supply some spectral properties of $(A, m)$-expansive operators. Some examples are discussed, too.
