http://jlta.iauctb.ac.ir/article_673753_1133993.html
We propose an efficient mesh-less method for functional integral equations. Its convergence analysis has been provided. It is tested via a few numerical experiments which show the efficiency and applicability of the proposed method. Attractive numerical results have been obtained.Sun, 31 May 2020 19:30:00 +0100Integral type contraction and coupled fixed point theorems in ordered G-metric spaces
http://jlta.iauctb.ac.ir/article_673785_1133993.html
In this paper, we apply the idea of integral type contraction and prove some coupled fixed point theorems for such contractions in ordered $G$-metric space. Also, we support the main results by an illustrative example.Sun, 31 May 2020 19:30:00 +0100Paracompactness on supra topological spaces
http://jlta.iauctb.ac.ir/article_673819_1133993.html
In this article, we present the concept of supra paracompact spaces and study its basic properties. We elucidate its relationship with supra compact spaces and prove that the property of being a supra paracompact space is weakly hereditary and topological properties. Also, we provide some examples to show some results concerning paracompactness on topology are invalid on supra topology. Finally, we investigate some results related to the product space and projection map.Sun, 31 May 2020 19:30:00 +0100Approximation of endpoints for multi-valued mappings in metric spaces
http://jlta.iauctb.ac.ir/article_673898_1133993.html
In this paper, under some appropriate conditions, we prove some $Delta$ and strong convergence theorems of endpoints for multi-valued nonexpansive mappings using modified Agarwal-O'Regan-Sahu iterative process in the general setting of 2-uniformly convex hyperbolic spaces. Our results extend and unify some recent results of the current literature.Sun, 31 May 2020 19:30:00 +0100Somewhat-connectedness and somewhat-continuity in the product space
http://jlta.iauctb.ac.ir/article_673884_1133993.html
In this paper, the concept of somewhat-connected space will be introduced and characterized. Its connection with the other well-known concepts such as the classical connectedness, the $omega_theta$-connectedness, and the $omega$-connectedness will be determined. Moreover, the concept of textit{somewhat}-continuous function from an arbitrary topological space into the product space will be characterized.Sun, 31 May 2020 19:30:00 +0100Some relations between $L^p$-spaces on locally compact group $G$ ...
http://jlta.iauctb.ac.ir/article_673999_1133993.html
Let $H$ and $K$ be compact subgroups of locally compact group $G$. By considering the double coset space $Ksetminus G/H$, which equipped with an $N$-strongly quasi invariant measure $mu$, for $1leq pleq +infty$, we make a norm decreasing linear map from $L^p(G)$ onto $L^p(Ksetminus G/H,mu)$ and demonstrate that it may be identified with a quotient space of $L^p(G)$. In addition, we illustrate that $L^p(Ksetminus G/H, mu)$ is isometrically isomorphic to a closed subspace of $L^p(G)$. These assist us to study the structure of the classical Banach space created on a double coset space by those produced on topological space.Sun, 31 May 2020 19:30:00 +0100Common fixed point results for graph preserving mappings in parametric $N_b$-metric spaces
http://jlta.iauctb.ac.ir/article_673949_1133993.html
In this paper, we discuss the existence and uniqueness of points of coincidence and common fixed points for a pair of graph preserving mappings in parametric $N_b$-metric spaces. As some consequences of this study, we obtain several important results in parametric $b$-metric spaces, parametric $S$-metric spaces and parametric $A$-metric spaces. Finally, we provide some illustrative examples to justify the validity of our main result. Sun, 31 May 2020 19:30:00 +0100
