Abstract:
Topological quivers are the broadest topological analogue of directed graphs, and may be used to construct C*-algebras. I will present a topological version of the combinatorial skew product and show how this designs a natural coaction on the associated C*-algebra. With classical intuition at hand, this develops a class of coactions which one can “see” in a noncommutative framework. I’ll gesture toward some work in progress generalizing these coactions to a broader setting.
