Abstract: We combine two aspects, fuzzy mathematics and partial functional differential equations to get fuzzy partial hyperbolic functional differential equations in the sense of generalized Hukuhara-differentiability. In this setting, the global existence of four solutions, each one corresponding to a different type of differentiability, is investigated in the whole infinite domain [a, ∞) × [b, ∞).
Keywords: Partial hyperbolic functional differential equations, fuzzy solution, Banach fixed point theorem, contraction operator, the continuity of Zadeh’s extension, generalized Hukuhara derivatives
