##### 1. A new subclass of harmonic mappings with positive coefficients

*Volume 08, Issue 03 , Summer 2019, Pages 159-165*

#####
**Abstract **

Complex-valued harmonic functions that are univalent and sense-preserving in the open unit disk $U$ can be written as form $f =h+\bar{g}$, where $h$ and $g$ are analytic in $U$. In this paper, we introduce the class $S_H^1(\beta)$, ...

##### 2. Invariant elements in the dual Steenrod algebra

*Volume 08, Issue 03 , Summer 2019, Pages 167-172*

#####
**Abstract **

In this paper, we investigate the invariant elements of the dual mod $p$ Steenrod subalgebra ${\mathcal{A}_p}^*$ under the conjugation map $\chi$ and give bounds on the dimensions of $(\chi-1)({\mathcal{A}_p}^*)_d$, where $({\mathcal{A}_p}^*)_d$ is the dimension of ${\mathcal{A}_p}^*$ ...

##### 3. $(F,\varphi ,\alpha )_{s}$-contractions in $b$-metric spaces and applications

*Volume 08, Issue 03 , Summer 2019, Pages 173-182*

#####
**Abstract **

In this paper, we introduce more general contractions called $\varphi $-fixed point point for $(F,\varphi ,\alpha )_{s}$ and $(F,\varphi ,\alpha )_{s}$-weak contractions. We prove the existence and uniqueness of $\varphi $-fixed point ...

*Volume 08, Issue 03 , Summer 2019, Pages 183-189*

#####
**Abstract **

This paper develops iterative method described by [V. Daftardar-Gejji, H. Jafari, An iterative method for solving nonlinear functional equations, J. Math. Anal. Appl. 316 (2006) 753-763] to solve Ito stochastic ...

##### 5. Ring endomorphisms with nil-shifting property

*Volume 08, Issue 03 , Summer 2019, Pages 191-202*

#####
**Abstract **

Cohn called a ring $R$ is reversible if whenever $ab = 0,$ then $ba = 0$ for $a,b\in R.$ The reversible property is an important role in noncommutative ring theory. Recently, Abdul-Jabbar et al. studied the reversible ring property on nilpotent elements, introducing the ...

##### 6. 2n-Weak module amenability of semigroup algebras

*Volume 08, Issue 03 , Summer 2019, Pages 203-209*

#####
**Abstract **

Let $S$ be an inverse semigroup with the set of idempotents $E$. We prove that the semigroup algebra $\ell^{1}(S)$ is always $2n$-weakly module amenable as an $\ell^{1}(E)$-module, for any $n\in \mathbb{N}$, where $E$ acts on $S$ trivially ...
