Abstract :
In this present work, we prove fixed point theorem for contractive mapping F: X × X → X in fuzzy metric spaces that have a nonempty F −invariant complete subspace E, then prove the uniqueness the fixed point in E. Though many theorems in fuzzy metric space in this case, our theorem is a new type of these theorems. because we prove unique fixed point is in F − invariant complete subset E in X. Finally, we give an interesting example in complete fuzzy metric space that satisfies in the conditions of our theorem.
