Abstract

In this paper, the notion of cyclic $\varphi$-contraction in fuzzy
metric spaces is introduced and a fixed point theorem for this type
of mapping is established. Meantime, an example is provided to
illustrate this theorem. The main result shows that a self-mapping
on a G-complete fuzzy metric space has a unique fixed point if it
satisfies the cyclic $\varphi$-contraction. Afterwards, some results in
connection with the fixed point are given.
