Ulam–Hyers stability of Caputo-type fractional fuzzy stochastic differential equations with delay. Communications in Nonlinear Science and Numerical Simulation, 121, 107229-1. https://doi.org/10.1016/j.cnsns.2023.107229.1007-57041878-7274https://hdl.handle.net/11441/147908We explore a new kind of Caputo-type fractional fuzzy stochastic differential equations (FFSDEs) with delay. We establish the existence result of FFSDEs with delay by monotone iterative technique combined with the method of upper and lower solutions, and then the uniqueness is proved. Subsequently, we study the Ulam–Hyers (U–H) stability. Finally, three examples with numerical simulations are provided to illustrate the theoretical results.application/pdf29 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Fuzzy stochastic differential equationsFractional calculusUlam–Hyers stabilityExistence and uniquenessinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1016/j.cnsns.2023.107229
