In this article, we establish the existence and uniqueness of
(c1)-differentiable and (c2)- differentiable solutions to first-order
nonlinear impulsive fuzzy differential equations under generalized Hukuhara
differentiability using the contraction mappings principle. In particular,
(c1)-differentiable solutions are written as hyperbolic cosine and sine
functions with impulsive terms, which is the main difficulty. An example is
provided to prove our results.
