Existence of triple best proximity point for a 3-cyclic summing Meir-Keeler contraction

Let , and be nonempty subsets of a matric space . Then the mapping is called cyclic if , and . Consider the following optimization problem Let , certainly if the condition be true for some then it is best answer for optimization problem , that we called it triple best proximity point of .In this paper‎, first ‎we introduce the notion of 3-cyclic summing Meir-Keeler contractions as a generalization of 3-cyclic summing contractions, then we obtain the conditions for the existence of a triple best proximity point for these class of mappings in the metric spaces with property UC‎. Our results in this paper are true for a n-cyclic summing Meir-Keeler contraction just we work with order 3 for the simplicity of proofs. Note that, our results are generalizations of some existing theorems with shorter and simpler proofs.
