TITLE: Isometric Circle Actions
ABSTRACT: I will begin by describing a number of important examples of isometric actions of circles in Euclidean space and their restrictions to subspaces of Euclidean space. The goal of the talk will be to see how isometric actions of circles can be used to "recognize" the space on which they are acting.
