  In earlier papers Saxena et al. (2002, 2003) derived the solutions of a
number of fractional kinetic equations in terms of generalized Mittag-Leffler
functions which extended the work of Haubold and Mathai (2000). The object of
the present paper is to investigate the solution of a unified form of
fractional kinetic equation in which the free term contains any integrable
function f(t), which provides the unification and extension of the results
given earlier recently by Saxena et al. (2002, 2003). The solution has been
developed in terms of the Wright function in a closed form by the method of
Laplace transform. Further we derive a closed-form solution of a fractional
diffusion equation. The asymptotic expansion of the derived solution with
respect to the space variable is also discussed. The results obtained are in a
form suitable for numerical computation.
