Some new fixed point theorems in Menger PM-spaces with application to Volterra type integral equation

We establish some fixed point theorems by introducing two new classes of contractive mappings in Menger PM-spaces. First, we prove our results for an αα-ψψ-type contractive mapping and then for a generalized ββ-type contractive mapping. Some examples and an application to Volterra type integral equation are given to support the obtained results.
