Lubetkin's Lenin Memorial

This conference paper summarised my recent research on the strange story of the Lenin Memorial erected in wartime London and destroyed shortly afterwards. It placed this episode within the wider context of iconoclasm and the destruction of public art. It was based on research that will contribute to my forthcoming book on the subjec

Entropy and induced dynamics on state spaces

We consider the topological entropy of state space and quasi-state space homeomorphisms induced from C*-algebra automorphisms. Our main result asserts that, for automorphisms of separable exact C*-algebras, zero Voiculescu-Brown entropy implies zero topological entropy on the quasi-state space (and also more generally on the entire unit ball of the dual). As an application we obtain a simple description of the topological Pinsker algebra in terms of local Voiculescu-Brown entropy.Comment: 16 pages; some revision; to appear in GAF
