On the fixed points of nonexpansive mappings in direct sums of Banach spaces
Andrzej Wiśnicki · Studia Mathematica · 2011
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
