Abstract
In this paper our main result is a coupled coincidence point theorem for a compatible pair in a fuzzy metric space with a partial ordering under the assumption of a new coupled contraction inequality which involves a recently introduced control function which is a generalization of many such functions previously used in literatures. The proof depends on a lemma in which we prove a condition for simultaneous holding of Cauchy criteria for two sequences. We use H-type t-norms in this paper in order to utilize the equi-continuity of the t-norm iterates in the proof of the lemma. The contraction inequality also involves another function which is borrowed from a recent work, there is a partial ordering defined on the fuzzy metric space. There are several corollaries of the main theorem. An illustrative example is given.
