Decomposing Pointwise Finite-Dimensional Representations of the Circle

ABSTRACT: Representations of the circle have appeared in very different contexts, which we will briefly discuss. Then we will discuss motivation for a unified definition and provide such a definition. We then show how pointwise finite-dimensional representations of the circle decompose analogously to type à quivers. Importantly, we do not obtain any strange new indecomposables due to the continuum. This is joint work with Eric J. Hanson.
