1. Intuitionistic fuzzy stability of the heptic functional equation
Volume 3, Issue 2 , Spring 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 ... Read More
2. On character amenability of weighted convolution algebras on certain semigroups
Volume 3, Issue 2 , Spring 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 ... Read More
3. Fixed point results for generalized contractions in S-metric spaces
Volume 3, Issue 2 , Spring 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 ... Read More
4. Some coupled coincidence point results in partially ordered metric spaces
Volume 3, Issue 2 , Spring 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 ... Read More
5. The coincidence point results and rational contractions in E(s)-distance spaces
Volume 3, Issue 2 , Spring 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 ... Read More
