Sorted by: 11. D is closed and bounded, and T compact, hence K = T ( D) ¯ ⊂ D is compact. Hence the convex hull co K is totally bounded, and C = co K ¯ ⊂ D is a compact convex nonempty set. The restriction T C: C → C is continuous. By the Schauder fixed point theorem, T C has a fixed point in C. Share.
