  Suppose that E is a Banach space, {\tau} a topology under which the norm of E
becomes {\tau}-lower semicontinuous and S a commuting family of
{\tau}-continuous nonexpansive mappings defined on a {\tau}-compact convex
subset C of E: It is shown that the set of common fixed points of S is a
nonempty nonexpansive retract of C. Along the way, a few other related fixed
point theorems are derived.
