Browder's Theorem with General Parameter Space

General Topology 2021-05-03 v1

Abstract

Browder (1960) proved that for every continuous function F:X×YYF : X \times Y \to Y, where XX is the unit interval and YY is a nonempty, convex, and compact subset of \dRn\dR^n, the set of fixed points of FF, defined by CF:={(x,y)X×Y ⁣:F(x,y)=y}C_F := \{ (x,y) \in X \times Y \colon F(x,y)=y\} has a connected component whose projection to the first coordinate is XX. We extend this result to the case where XX is a connected and compact Hausdorff space.
