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 ##submission.copyrightStatement## Mon, 22 Jan 2018 16:06:21 +0000 On semi-compact and semi-Lindelof Quotient Radon measure manifolds and their intrinsic structures <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.

In this paper we study the \(t\)-representability of maximal subgroups of the symmetric group.</p> Sini P ##submission.copyrightStatement## Sat, 17 Feb 2018 12:02:50 +0000 A property of hyperbolic general family of function spaces with Hadamard gap series <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 \(&nbsp;f(z)= \sum_{k=1}^{\infty} a_{k}z^{n_k}\) satisfying \(\frac{n_{k+1}}{n_k}\geq \lambda &gt; 1\) for all \(k\), to belong to \(F^{*}{(p,q,s)}\) and&nbsp;\(F^{*}_{0}{(p,q,s)}\) on the unite disk \(\mathbb{D}\).</p> A.

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 ##submission.copyrightStatement## Fri, 23 Mar 2018 12:34:47 +0000 A study on fuzzy irresoulte topological Vector spaces <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.
