Abstract

In this paper we introduce the concepts of \(c-C_{\alpha\beta}-\)admissible mapping, \((\alpha\beta)_c-\Theta-\)contraction, weak \((\alpha\beta)_c-\Theta-\)contraction, generalized \((\alpha\beta)_c-\Theta-\)contraction and establish the existence of PPF dependent fixed point theorems for such classes of contractive nonself-mappings in the Razumikhin class. We give, also, a result of existence of a PPF dependent fixed point by a condition of Suzuki type. As applications of our theorems, we deduce some PPF dependent fixed point theorems for nonself-mappings valued in a Banach space endowed with a graph or a partial order, and furnish an illustrative example to support our main theorem.
