A variant of fixed point theorem is proved in the setting of S-metric spaces

the present note arises from the author's talk at the conference ``ischia group theory 2014''. for subgroups $fle n$ of a group $g$ denote by $lat(f,n)$ the set of all subgroups of $n$, containing $f$. let $d$ be a subgroup of $g$. in this note we study the lattice $ll=lat(d,g)$ and the lattice $ll'$ of subgroups of $g$, normalized by $d$. we say that $ll$ satisfies sandwich classification theo...

n this article, we prove An Lp-Lq-version of Morgan’s theorem for the generalized Bessel transform.

In this paper, a common fixed point theorem for $psi$-weakly commuting maps in L-fuzzy metric spaces is proved.

In this paper we introduce the cone bounded linear mapping and demonstrate a proof to show that the cone norm is continuous. Among other things, we prove the open mapping theorem and the closed graph theorem in TVS-cone normed spaces. We also show that under some restrictions on the cone, two cone norms are equivalent if and only if the topologies induced by them are the same. In the sequel, we...

In some long term studies, a series of dependent and possibly truncated lifetime data may be observed. Suppose that the lifetimes have a common continuous distribution function F. A popular stochastic measure of the distance between the density function f of the lifetimes and its kernel estimate fn is the integrated square error (ISE). In this paper, we derive a central limit theorem for t...

Let M be an m-dimensional complex manifold. We recall the definition of the Kobayashi-Royden pseudo-metric on M : FM (ξ) = inf{t > 0| ∃f ∈ O(∆,M) such that tf∗(d/dζ|ζ=0) = ξ}, (1.1) where ξ ∈ T pM is a holomorphic tangent vector, ∆ = {ζ ∈ C| |ζ| < 1}, and O(∆,M) = {f : ∆ → M | f is a holomorphic mapping}. Then, FM has the following properties: (i) FM (ξ) ≥ 0 for any ξ ∈ T pM ; (ii) FM (λξ) = |λ...

‎in this paper, based on [a. razani, v. rako$check{c}$evi$acute{c}$ and z. goodarzi, nonself mappings in modular spaces and common fixed point theorems, cent. eur. j. math. 2 (2010) 357-366.] a fixed point theorem for non-self contraction mapping $t$ in the modular space $x_rho$ is presented. moreover, we study a new version of krasnoseleskii's fixed point theorem for $s+t$, where $t$ is a cont...

in this paper, we introduce intuitionistic fuzzy contraction mappingand prove a fixed point theorem in intuitionistic fuzzy metric spaces.
