In this paper, we introduce a new type of multi-valued -contraction mapping on a metric space endowed with a directed graph
and prove an existence theorem for fixed point problems in metric space endowed with a graph. Moreover, we prove fixed point theorems in partially ordered metric spaces by our main result. Some examples illustrating our main results are also present.
