On super-rigid and uniformly super-rigid operators

Abstract

An operator TT acting on a Banach space XX is said to be super-recurrent if for each open subset UU of XX, there exist λK\lambda\in\mathbb{K} and nNn\in \mathbb{N} such that λTn(U)U\lambda T^n(U)\cap U\neq\emptyset. In this paper, we introduce and study the notions of super-rigidity and uniform super-rigidity which are related to the notion of super-recurrence. We investigate some properties of these classes of operators and show that they share some properties with super-recurrent operators. At the end, we study the case of finite-dimensional spaces.
