##### 1. Approximate solutions of homomorphisms and derivations of the generalized Cauchy-Jensen functional equation in $C^*$-ternary algebras

*Volume 09, Issue 01 , Winter 2020, Pages 1-15*

#####
**Abstract **

In this paper, we prove Hyers-Ulam-Rassias stability of $C^*$-ternary algebra homomorphism for the following generalized Cauchy-Jensen equation $$\eta \mu f\left(\frac{x+y}{\eta}+z\right) = f(\mu x) + f(\mu y) +\eta f(\mu z)$$ for all $\mu \in \mathbb{S}:= \{ \lambda \in \mathbb{C} : |\lambda | =1\}$ ...

##### 2. Fixed points of generalized $\alpha$-Meir-Keeler type contractions and Meir-Keeler contractions through rational expression in $b$-metric-like spaces

*Volume 09, Issue 01 , Winter 2020, Pages 17-34*

#####
**Abstract **

In this paper, we first introduce some types of generalized $\alpha$-Meir-Keeler contractions in $b$-metric-like spaces and then we establish some fixed point results for these types of contractions. Also, we present a new fixed point theorem for a Meir-Keeler contraction through rational expression. ...

##### 4. Fixed point results for Su-type contractive mappings with an application

*Volume 09, Issue 01 , Winter 2020, Pages 53-65*

#####
**Abstract **

In this paper, we introduce the concept of Su-type contractive mapping and establish fixed point theorems for such mappings in the setting of ordered extended partial $b$-metric space. We also develop an application for Fredholm type integral equations ...

##### 5. On the topological equivalence of some generalized metric spaces

*Volume 09, Issue 01 , Winter 2020, Pages 67-74*

#####
**Abstract **

The aim of this paper is to establish the equivalence between the concepts of an $S$-metric space and a cone $S$-metric space using some topological approaches. We introduce a new notion of a $TVS$-cone $S$-metric space using some facts about ...

##### 6. Multi-valued fixed point theorems in complex valued $b$-metric spaces

*Volume 09, Issue 01 , Winter 2020, Pages 75-94*

#####
**Abstract **

The aim of this paper is to establish and prove some results on common fixed point for a pair of multi-valued mappings in complex valued $b$-metric spaces. Our results generalize and extend a few results in the literature.
