Recurrence of Composition Operators on Discrete Banach Spaces

Let (T,d) be an unbounded and locally finite metric space that contains a distinguished element o. Let L∞(T) denote the discrete Banach space and L0(T) its subspace of functions vanishing at infinity. First, we establish that the recurrence of a composition operator on the L0(T) space is equivalent to its rigidity. We then provide an equivalent characterization for the uniformly rigid and F-recurrence of Cφ. For the L∞(T) space, the recurrence of the operator is equivalent to the periodicity of the function φ. Second, we explore the concept of disjoint topological recurrence associated with multiple composition operators.

Abstract

Let (T,d) be an unbounded and locally finite metric space that contains a distinguished element o. Let L∞(T) denote the discrete Banach space and L0(T) its subspace of functions vanishing at infinity. First, we establish that the recurrence of a composition operator on the L0(T) space is equivalent to its rigidity. We then provide an equivalent characterization for the uniformly rigid and F-recurrence of Cφ. For the L∞(T) space, the recurrence of the operator is equivalent to the periodicity of the function φ. Second, we explore the concept of disjoint topological recurrence associated with multiple composition operators.
