Typical Uniqueness in Ergodic Optimization

Dynamical Systems 2025-06-03 v1

Abstract

For ergodic optimization on any topological dynamical system, with real-valued potential function ff belonging to any separable Banach space BB of continuous functions, we show that the ff-maximizing measure is typically unique, in the strong sense that a countable collection of hypersurfaces contains the exceptional set of those fBf\in B with non-unique maximizing measure. This strengthens previous results asserting that the uniqueness set is both residual and prevalent.
