Abstract

We show that if a Banach space $X$ has the weak fixed point property for nonexpansive mappings and $Y$ has the generalized Gossez–Lami Dozo property or is uniformly convex in every direction, then the direct sum $X\oplus Y$ with a strictly monotone norm has the weak fixed point property. The result is new even if $Y$ is finite-dimensional.
