A fractional integro-differential equation of volterra type

An analytical and numerical treatment of a fractional integro-differential equation has been considered recently by Boyadjiev et al. [1]. This paper deals with a fractional generalization of the Free Electron Laser (FEL) equation, and the solution is obtained by a method that combines the variation of parameters and successive approximations. The numerical values have been obtained employing the algebra system MAPLE V.
