In this paper we establish Hyers-Ulam-Rassias stability and Hyers-Ulam Criteria for second order non-linear ordinary differential equations of Lane-Emden type; moreover two examples of such equations are considered

In this paper, using “belongingness (∈) ” and quasi-coincidence (q) ” of fuzzy points and" fuzzy sets, the concept of (∈, ∈ ∨q) -fuzzy hemirings and (∈¯, ∈ ∨¯ ¯q) -fuzzy hemirings have been introduced and some of its properties have been investigate
The aim of this paper is to introduce and study the notions of µ-semicompactness and strong µ-semi-compactness in generalized topological spaces with respect to a hereditary class, called µH-semi-compactness and S-µH-semicompactness, respectively. Also several of their ...
In this paper, we establish the concept of non-self Hardy-Rogers contractions on Banach spaces involving a graph. We also prove some ﬁxed point theorems for such mappings. The results of this paper extend and generalize various known results in the literature.
In this work, we establish several results about the existence of fuzzy solutions for some Fuzzy Neutral partial integro-Diﬀerential Equation with nonlocal condition. Our approach rest on the Banach ﬁxed-point theorem.
In literature many solution of Einstein-Maxwell’s equations have been found. We consider the spherically symmetric geometry and classify the solutions of Einstein-Maxwell’s equations by considering the null/non-null electromagnetic ﬁeld and isotropic/anisotropic matter ...
