Abstract
We introduce the concept of an alpha(c)-admissible non-self-mappings with respect to eta(c) and establish the existence of PPF dependent fixed and coincidence point theorems for alpha(c)eta(c)-psi-contractive non-self-mappings in the Razumikhin class. As applications of our PPF dependent fixed point and coincidence point theorems, we derive some new fixed and coincidence point results for psi-contractions whenever the range space is endowed with a graph or with a partial order. The obtained results generalize, extend, and modify some PPF dependent fixed point results in the literature. Several interesting consequences of our theorems are also provided.
