Variational homotopy perturbation method for the rst order linear fuzzy di erential equations

In this paper, Variational homotopy perturbation method for solving rst order linear fuzzy di erential equations under generalized di erentiability is proposed. In a recent paper, A. Noor in [Mathematical Problems in Engineering,2008,Article ID 696734,11 pages] proposed Variational homotopy perturbation method (VHPM) for a special kind of nonlinear di erential equations
