초록

The aim of this paper is to prove a common fixed point theo- rem in normed linear spaces for discontinuous, occasionally weakly biased mappings without assuming completeness of the space. We give an exam- ple to illustrare our theorem. We also give an application of our theorem to best approximation theory. Our theorem improve the results of Gre- gus [9], Jungck [12], Pathak, Cho and Kang [22], Sharma and Deshpande [26]-[28].

Abstract
