Abstract:
This talk explores the stable uniqueness results established in Sections 4 and 5 of Rufus Willett’s Conditional Representation Stability, -Homomorphisms, and Eta Invariants. We will focus on their implications for the approximation problem of quasi-representations. Specifically, we examine whether every quasi-representation of a surface group is close to an actual representation, and discuss possible obstructions when this approximation fails. Our analysis underscores the significance of stable uniqueness in resolving approximation challenges within the C-algebraic framework.
