Abstract: We consider two nonindependent random fields $$\psi $$ψ and $$\phi $$ϕ defined on a countable set Z. For instance, $$Z=\mathbb {Z}^d$$Z=Zd or $$Z=\mathbb {Z}^d\times I$$Z=Zd×I, where I denotes a finite set of possible “internal degrees… read more here.

Abstract: In this article, we study a new generalized multivalued Khan-type (ψ,ϕ)$(\psi ,\phi )$-contraction. We obtain some fixed point theorems related to the introduced contraction for multivalued mappings in complete metric spaces. Our theorems extend and… read more here.
