Some Common Coupled Fixed Point Results on Modified Intuitionistic Fuzzy Metric Spaces

Procedia Computer Science, 2016
AbstractThe core purpose of this paper is to prove fixed point results by using the concept of modified intuitionistic fuzzy metric space. For the coupled maps, we first formulate the definition of E.A property and common property (E.A) property on modified intuitionistic fuzzy metric space.
