http://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1370
<p>N. Souayah [10] introduced the concept of partial Sb-metric spaces. In this paper, we established a fixed point theorem for a new class of contractive mappings and a generalization of Theorem 2 from [T. Suzuki, A generalized Banach contraction principle that characterizes metric completeness, Proc. Am. Math. Soc. 136, (2008), 1861-1869] in partial Sb-metric spaces. We provide an example in support of our result.</p>Koushik Sarkar, Manoranjan Singha

http://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1321
<pre>In this paper the invariance of Radon measure structure is studied on measurable semi-compact and measurable semi-Lindelof Quotient measure manifolds under measurable homeomorphism and Radon measure structure-invariant map to generate categories of measurable semi-compact and measurable semi-Lindelof Quotient Radon measure manifolds.</pre>S.

http://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1294
<p>A subgroup \(H\) of the group \(S(X)\) of all permutations of a set \(X\) is called \(t\)−representable on \(X\) if there exists a topology \(T\) on \(X\) such that the group of homeomorphisms of \((X, T ) = K\). In this paper we study the \(t\)-representability of maximal subgroups of the symmetric group.</p>Sini P

http://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1324
<p>In this article, we obtained results which characterized the hyperbolic general family functions \(F^{*}{(p,q,s)}\) and \(F^{*}_0{(p,q,s)}\) by the coefficients of certain lacunary series expansions in the unit disk. Moreover, we obtain a sufficient and necessary condition for the hyperbolic function \(f^*\) with Hadamard gaps, that is, for \( f(z)= \sum_{k=1}^{\infty} a_{k}z^{n_k}\) satisfying \(\frac{n_{k+1}}{n_k}\geq \lambda > 1\) for all \(k\), to belong to \(F^{*}{(p,q,s)}\) and \(F^{*}_{0}{(p,q,s)}\) on the unite disk \(\mathbb{D}\).</p>A.

http://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1383
<p>In this work, we will introduce the notion of i-continuity and d-continuity of the functions between the ordered closure spaces. Then, we give a classication of the closure operators defined on the set of i-continuous and d-continuous functions.</p>Irem eroğlu, Erdal Guner

http://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1384
<p>In this paper, our focus is to investigate the notion of fuzzy irresolute topological vector spaces. Fuzzy irresolute topological vector spaces are defined by using fuzzy \(rho\)-open sets and fuzzy irresolute functions. Some of their properties and characterizations are also discussed.</p>V.

http://m-sciences.com/index.php?journal=jast&page=article&op=view&path%5B%5D=1408
<p>In this paper we examine some topological properties of soft fuzzy metric space which introduced in [5].<br>We dene the concepts such as countability, convergence, completeness in soft fuzzy metric spaces and also<br>we establish some related theorems to this denitions.</p>Ferhan Sola Erduran, Ebru Yigit, Rabia Alar, Ayten Gezici
