SOME REMARKS ON FIXED POINTS

DO HONG TAN, HA DUC VUONG

Abstract

In this note we establish two independent results on fixed points. The first one is about the continuity of fixed points of limit-compact mappings introduced by Sadovskii in [7]. This result partially generalizes a result of Tan in [10] for collectively condensing mappings. The second result is a new fixed point theorem for the sum of a generalized contraction and a compact mapping, which improves a well-known result of Krasnoselskii [4]. A probabilistic version of this result is also presented here.
