“…The stability problems of several functional equations have been extensively investigated by a number of authors and there are many interesting results concerning this problem (see [1,3,24,31,34,35,39,42,44,50,66,57], [60]- [62]). …”
Abstract. Using the fixed point method, we prove the Hyers-Ulam stability of an additive-quadratic-cubic-quartic functional equation in matrix fuzzy normed spaces.

“…In 1978, Rassias [3] provided a remarkable generalization of the Ulam-Hyers stability of mappings by considering variables. During the last two decades very important contirbutions to the stability problems of functional equations were given by many mathematicians (see [4][5][6][7][8][9][10][11]). A generalization of Ulam's problem was recently proposed by replacing functional equations with differential equations: The differential equation F (t, y(t), y ′ (t), ..., y (n) (t)) = 0 has the Hyers-Ulam stability if for given ε > 0 and a function y such that…”
Abstract:In this paper we establish Hyers-Ulam and Hyers-Ulam-Rassias stability for fractional integrodifferential equationswith the initial condition x (α−1) (t0) = x0.
“…Rassias' Theorem. During the last two decades a number of papers and research monographs have been published on various generalizations and applications of the Hyers-Ulam stability to a number of functional equations and mappings (see [12,13,18]). …”
Abstract. In this paper, we investigate additive functional inequalities in paranormed spaces. Furthermore, we prove the HyersUlam stability of additive functional inequalities in paranormed spaces.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
