Moreover, this theorem applies equally well to continuous logic, and is also valid for formulas that are only stable with respect to a fixed model. In this talk, we examine how this connection applies to stable group theory. We develop the foundations of stable group theory directly from topological dynamics and, in particular, results of Ellis and Nerurkar on weakly almost periodic flows (which are ba ... |
