Abstract
In this study, we introduce new concepts of α − FZ -contraction and α − ψ − FZ -contraction and we discuss existence results of the best proximity points of such types of non-self-mappings involving control functions in the structure of complete fuzzy metric spaces. Our results extend, generalize, enrich, and improve diverse existing results in the current literature.

Khojasteh et al [23] presented an impressive technique to the investigation of fixed point theory by developing the notion of simulation functions, which exhibit a significant unifying power. e idea of simulation functions has been generalized, improved, and extended in different metric spaces
E best proximity theory is another expanding and prominent aspect of fixed point theory which plays a fundamental role in the investigation of requirements that guarantee the existence of an optimal approximate fixed point when the functional equation Lx x has no solution
Summary
Recent advancements in fixed point theory are one of the central and active research areas of nonlinear functional analysis, which provides a variety of mathematical methods, principles, and techniques for solving a variety of problems arising from various branches of mathematics as well as various fields in science and engineering. e Banach fixed point theorem is considered as one of the most fruitful results in this theory. In the present study, following this line of research interest, we present a simulation function approach to best proximity point problems in fuzzy metric spaces. Let Ψ be the class of nondecreasing functions ψ: (0, 1] ⟶ (0, 1] fulfilling the following two conditions: (ψ1) ψ is continuous (ψ2) ψ(c) > c for all c ∈ (0, 1) A self-mapping L: Λ ⟶ Λ on a fuzzy metric space (Λ, D, ∗) is called a fuzzy ψ-contractive mapping if
