“…Proving whether Theorems 2 and 3 remain true if we replace R-weakly commutativity of type A f (or type A g ) with some other concept of commutativity of two self-mappings in the weaker sense. A positive answer for Theorem 2 in this sense was obtained by Ješić et al [19] for a pair of semi R-commuting mappings;…”

“…The first result from the fixed point theory in probabilistic metric spaces was obtained by Sehgal and Bharucha-Reid [15]. Since then, the fixed and common fixed point theorems for various contraction mappings in probabilistic metric spaces were investigated by many authors (see e.g., [16][17][18][19][20][21][22][23]).…”
The purpose of this paper is to prove that orbital continuity for a pair of self-mappings is a necessary and sufficient condition for the existence and uniqueness of a common fixed point for these mappings defined on Menger PM-spaces with a nonlinear contractive condition. The main results are obtained using the notion of R-weakly commutativity of type Af (or type Ag). These results generalize some known results.

In this paper we prove existence and uniqueness of a common fixed point for non-self coincidentally commuting mappings with nonlinear, generalized contractive condition defined on strictly convex Menger PM-spaces proved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
