Title:Gelfand duality and Ramsey theory
Seminar:Logic Seminar
Speaker:Willem Fouché, University of South Africa
Abstract:
In this talk, I want to discuss recent developments arising from the paper [1] (1987). In this paper, Andreas Blass introduced the idea of, what he called, a Ramsey action of a group on a discrete space in the context of understanding the tension, in set theory, between the Axiom of Choice and the Prime Ideal Theorem for Boolean algebras. In this talk, I will discuss this very tension, with the benefit of hindsight, as to what has happened to his viewpoint as viewed from the world of the dynamical aspects of structural Ramsey theory. Some recent links with Gelfand duality of commutative C∗- algebras will be discussed.
