摘要
The main result of this paper is a fixed point theorem of self mappings in Menger spaces which satisfy certain inequality. This inequality involves a class of real functions which we call Phi-functions. As a corollary we obtain a result in the corresponding metric spaces. The result is supported by an example. The class of real functions we have used is the conceptual extension of altering distance functions used in metric fixed point theory.
