<i>J</i>-nonexpansive mappings in uniform spaces and applications
The purpose of the paper is to introduce a class of “ j -nonexpansive” mappings and to prove fixed point theorems for such mappings. They naturally arise in the existence theory of functional differential equations. These mappings act in spaces without specific geometric properties as, for instance, uniform convexity. Critical …
