In this paper, using the properties of a differential and integral calculus for fuzzy set valued mappings and completeness of metric space of fuzzy numbers, the global existence, uniqueness and the continuous dependence of a solution on a fuzzy differential equation are derived under the dissipative

β¦ Synopsis
The existence theorem of Peano for the fuzzy differential equation,
does not hold in general except in the special case where the fuzzy number space (E '~, D) is finite dimensional [1] or f is assumed to be continuous and bounded [2]. In this paper, the dissipative-type conditions which guarantee the existence theorem for Peano are specified based on the existence theorem of approximate solutions to above Cauchy problem. @

In this paper, the existence and uniqueness of a fuzzy solution for the semilinear fuzzy integrodifferential equation is established via the Banach fixed-point analysis approach and using the fuzzy number whose values are normal, convex upper semicontinuous, and compactly supported interval in EN.
This work is concerned with a class of nonlinear fuzzy neutral functional differential equations. Specifically, existence and uniqueness of fuzzy solutions for the nonlinear fuzzy neutral functional differential equation where A is a fuzzy coefficient and f and g are continuous functions, are estab
