摘要:We establish the existence and uniqueness of solutions for a class of nonlinear Volterra integral and integro-differential equations using fixed-point theorems for a new variant of cyclic ( φ , ψ , θ ) -contractive mappings. Nontrivial examples are given to support the usability of our results. MSC:47H10, 54H25.
