Fractional Derivatives, Memory Kernels and Solution of a Free Electron Laser Volterra Type Equation

The high gain free electron laser (FEL) equation is a Volterra type integro-differential equation amenable for analytical solutions in a limited number of cases. In this note, a novel technique, based on an expansion employing a family of two variable Hermite polynomials, is shown to provide straigh...
