In this manuscript, we establish some fixed point results for fuzzy mappings via ðα

results, some nontrivial examples are presented. Few interesting consequences are also stated which authenticate that our results
generalize many existing ones in the literature.
1. Introduction
Fixed point theory has attained an important and significant
role in analysis. The literature of the last four decades orna-
mented with results which discover fixed points of self and
non-self nonlinear operators in a metric space. This branch
of mathematics provides a strong tool for finding out the
solution of integral, differential, and eigenvalue equations.
Since 1922, the Banach contraction principle (BCP) has
become the center of the attention for researchers working
in different areas. The eminent Banach contraction principle
(BCP) [1] states that for a complete metric space ðΩ, dÞ,
each self-mapping η on Ω satisfying

ð Þ ≤ λd ξ

ð Þ,∀ξ

∈ Ω, where λ ∈ 0, 1 ½ Þ ð1Þ
has a unique fixed point.
A lot of literature can be found on generalizations and
extensions of the famous BCP by changing either the space
under consideration or the condition on the mapping. In
recent years, various authors presented interesting generaliza-
tions of a metric space, for example, uniform space [2, 3], b
-metric space [4], C
∗
-algebra valued metric space [5, 6], G
p
b
-metric space [7], and b
2
-metric space [8].
A very interesting generalization of metric space is cone
metric space. Gupta and Chauhan [9] presented an analo-
gous to the BCP on cone b-metric spaces in 2021. In con-
trast, Wardowski [10] extended the Banach contraction to
a more generalized form, known as F -contractions, and
established a fixed point theorem in complete metric spaces.
Furthermore, many mathematicians used F -contractions for
the existence of a fixed point, see [11–13]. Nadler’s theorem
[14] states that for a complete metric space ðΩ, dÞ, each non-
self-mapping η : Ω ⟶ CðΩÞ satisfying

∈ Ω, where λ ∈ 0, 1 ½ Þ ð2Þ
has a fixed point. Here, H denotes the Hausdorff metric
defined on CðΩÞ, the set of bounded and closed subsets of
Ω. Throughout the article, a b − metric space and a fuzzy
fixed point are denoted by a bms and a ffp, respectively.
Some important definitions are presented before construct-
ing the main results. These definitions are inevitable for next
discussion.
