Journal of Linear and Topological Algebra (JLTA) is an international mathematical journal founded at the middle of 2012. This journal is published by the IAU, Central Tehran Branch, and it appears four times a year. All papers published by Journal of Linear and Topological Algebra are rigorously peer reviewed, free of charge and open access. Articles that have previously been published, fully or in part, in a conference proceedings or else, should not be submitted to Journal of Linear and Topological Algebra for publication.

AIM AND SCOPE

Journal of Linear and Topological Algebra publishes original papers that advance study of linear algebra, topological algebras and their numerous applications. Particularly papers are sought that contribute new information to one of the fields of functional analysis and operator theory, convex analysis, matrix analysis, control and optimization, combinatorial linear algebra, ring theory and module theory, numerical linear algebra or immediate application of any of these fields to other branches of mathematics, including (but not limited to), differential equations, mathematical physics, geometry and probability.

1. Continuity of some mappings on a group via semi-regular topology

M. Ram; S. K. Elagan

Volume 10, Issue 03 , Summer 2021, Pages 179-185

Abstract
‎For a given topological space $(X‎, ‎~\Im)$,‎ ‎there is a coarser topology on $X$ which is called the semi-regular topology on $X$ (generated by regularly open subsets) and it is denoted by $\Im^{\delta}$‎. ‎In this paper‎, ‎we study the continuity of the group operation ...  Read More

2. An algebraic perspective on neutrosophic sets: fields and linear spaces

V. Cetkin; B. Pazar Varol; H. Aygun

Volume 10, Issue 03 , Summer 2021, Pages 187-198

Abstract
In this work, we intend to introduce and study another algebraic structure of single-valued neutrosophic sets called neutrosophic field as a continuation of our investigations on neutrosophic algebraic structures. For this goal, we define the concept of neutrosophic fields and observe some of their basic ...  Read More

3. A closure operator versus purity

M. Ghorbani

Volume 10, Issue 03 , Summer 2021, Pages 199-203

Abstract
‎Any notion of purity is normally defined in terms of‎ ‎solvability of some set of equations‎. ‎To study mathematical notions‎, ‎such as injectivity‎, ‎tensor products‎, ‎flatness‎, ‎one needs to have some categorical and‎ ‎algebraic ...  Read More

4. Projective system of topological quasi modules

S. Jana; S. Mazumder

Volume 10, Issue 03 , Summer 2021, Pages 205-216

‎Quasi module is a new algebraic structure‎, ‎based on module‎, ‎which is composed of a semigroup structure and a partial order accompanied with an external ring multiplication‎. ‎We proposed this structure in our paper \cite{qmod} while we were studying the hyperspace $\com{M}{} ...

Azadi Volume 10, Issue 03 , Summer 2021, Pages 225-233 Abstract ‎For a given positive integer$n$‎, ‎the$n^{th}$commutativity degree‎ ‎of a finite non-commutative semigroup$S$is defined to be the‎ ‎probability of choosing a pair$(x,y)$for$x‎, ‎y \in S$such‎ ‎that$x^n$and$y$commute in$S$‎. ‎If for every ...

Jahanshahloo Volume 05, Issue 03 , Summer 2016, , Pages 155-174 Abstract The efficiency measurement is a subject of great interest. The majority of studies on DEA models have been carried out using radial or non-radial approaches regarding the application of DEA for the efficiency measurement. This paper, based on the directional distance function, proposes a new generalized ... Read More Functional analysis 2. Classical Wavelet Transforms over Finite Fields A. Ghaani Farashahi Volume 04, Issue 04 , Autumn 2015, , Pages 241-257 Abstract This article introduces a systematic study for computational aspects of classical wavelet transforms over finite fields using tools from computational harmonic analysis and also theoretical linear algebra.

Volume 06, Issue 04 , Autumn 2017, , Pages 289-300

Abstract
In this paper, we introduce a pair of generalized proximal contraction mappings and prove the existence of a unique best proximity point for such mappings in a complete metric space. We provide examples to illustrate our result. Our result extends some of the results in the literature.  Read More

Volume 04, Issue 01 , Winter 2015, , Pages 25-34

Abstract
We give some new results on sparse signal recovery in the presence of noise, for weighted spaces. Traditionally, were used dictionaries that have the norm equal to 1, but, for random dictionaries this condition is rarely satisfied. Moreover, we give better estimations then the ones given ...  Read More

Abstract
In this paper we get some results and applications for duals and approximate duals of g-frames in Hilbert spaces. In particular, we consider the stability of duals and approximate duals under bounded operators and we study duals and approximate duals of g-frames in the direct sum of Hilbert spaces. We ...  Read More
