##### 1. Preclosure operator and its applications in general topology

A. A. Nasef; S. Jafari; M. Caldas; R. M. Latif; A. A. Azzam

Volume 07, Issue 01 , Winter 2018, Pages 1-9

##### Abstract
In this paper, we show that a pointwise symmetric pre-isotonic preclosure function is uniquely determined the pairs of sets it separates. We then show that when the preclosure function of the domain is pre-isotonic and the pre-closure function of the codomain is pre-isotonic and pointwise-pre-symmetric, functions ...  Read More

##### 2. On characterizations of weakly $e$-irresolute functions

M. Ozkoc; T. Yilmaz

Volume 07, Issue 01 , Winter 2018, Pages 11-19

##### Abstract
The aim of this paper is to introduce and obtain some characterizations of weakly $e$-irresolute functions by means of $e$-open sets defined by Ekici [6]. Also, we look into further properties relationships between weak $e$-irresoluteness and separation axioms and completely $e$-closed graphs.  Read More

##### 3. Transformations computations‎: ‎Power‎, ‎Roots and Inverse

M. Ghorbanzadeh; H. Kamali; A. Mansoori

Volume 07, Issue 01 , Winter 2018, Pages 21-38

##### Abstract
‎This paper presents some results of an annihilated element in Banach algebra‎, ‎and in specific case‎, ‎for any square matrix‎. The developed method significantly improves the computational aspects of transformations calculus and especially for finding powers and roots of any ...  Read More

##### 4. Applications of fuzzy $e$-open sets

Volume 07, Issue 01 , Winter 2018, Pages 39-51

##### Abstract
The aim of this paper is to introduce and study the notions of fuzzy upper $e$-limit set, fuzzy lower $e$-limit set and fuzzy $e$-continuously convergent functions. Properties and basic relationships among fuzzy upper $e$-limit set, fuzzy lower $e$- limit set and fuzzy $e$-continuity are investigated ...  Read More

##### 5. Symbolic computation of the Duggal transform

D. Pappas; V. Katsikis; I. Stanimirovic

Volume 07, Issue 01 , Winter 2018, Pages 53-62

##### Abstract
Following the results of \cite{Med}, regarding the Aluthge transform of polynomial matrices, the symbolic computation of the Duggal transform of a polynomial matrix $A$ is developed in this paper, using the polar decomposition and the singular value decomposition of $A$. Thereat, the polynomial ...  Read More
