1. Intuitionistic fuzzy stability of the heptic functional equation
Volume 3, Issue 2 , June 2021, Pages 1-14
Abstract
In this article, by using a fixed point method, we establish the intuitionistic fuzzy version of Hyers-Ulam stability for a heptic functional equation that was introduced by Xu and Rassias. This way shows that the concept of stability is related to some fixed point of a suitable operator. Read More2. On character amenability of weighted convolution algebras on certain semigroups
Volume 3, Issue 2 , June 2021, Pages 15-26
Abstract
In this work, we study the character amenability of weighted convolution algebras $\ell^{1} (S,\omega)$, where $ S $ is a semigroup of classes of inverse semigroups with a uniformly locally finite idempotent set, inverse semigroups with a finite number of idempotents, Clifford semigroups and Rees matrix ...

Volume 3, Issue 2 , June 2021, Pages 27-39
Abstract
In this paper, we discuss the existence of a fixed point for a generalized contraction in S-metric spaces. We furnish some examples in support of our main results. Our results generalize and improve many well-known results in the existing literature. Read More4. Some coupled coincidence point results in partially ordered metric spaces
Volume 3, Issue 2 , June 2021, Pages 40-54
Abstract
In this paper, we introduce the notion of partial-compatibility of mappings in an ordered partial metric space and use this notion to establish coupled coincidence point theorems for $\phi$-mixed monotone mappings satisfying a nonlinear contraction condition. Our consequences is an extension of the results ... Read More5. The coincidence point results and rational contractions in E(s)-distance spaces
Volume 3, Issue 2 , June 2021, Pages 55-67
Abstract
The purpose of this article is to clarify the concept of semi-interior points of positive cones by presenting some results and examples in this context. Moreover, the new concept of E(s)-distance spaces is defined, which generalizes $E$-metric spaces. In addition, some coincidence point results ... Read More6.
