Title:Definability in Dynamical Systems
Seminar:Logic Seminar
Speaker:Henry Towsner, UCLA
The Furstenberg correspondence principle relates statements about finitary combinatorics to statements about (infinitary) dynamical systems. When we view this correspondence as a property of formulas in a suitable language, we discover that deep results of combinatorics, like the Szemeredi Regularity Lemma, correspond to logical statements about definability. We'll discuss a general approach to the correspondence principle and describe the interesting logical features of the models we obtain, and how we can use those features to derive combinatorial results.
