Abstract
In this paper we study the spectral properties of (m, C)-isometric operators. In particular, if T∈ L(H) is (m, C)-isometric operators, then the power of (m, C)-isometric operators is also (m, C)-isometric operators. Moreover, if T∗ has the single-valued extension property, then T has the single-valued extension property. Finally, we investigate conditions for (m, C)-isometric operators to be (1, C)-isometric operators. © 2016, Springer International Publishing.
