چکیده
|
In this paper, we introduce the (g-ψ) contraction in a metric space by using a graph. let t be a multivalued mappings on x. among other things, we obtain a fixed point of the mapping t in the metric space x endowed with a graph g such that the set of vertices of g, v (g) = x and the set of edges of g, e(g) ⊆ x × x.
