On the Laguerre fractional integro-differentiation

A fractional power interpretation of the Laguerre derivative $(DxD)^\alpha,\ D\equiv {d\over dx}$ is discussed. The corresponding fractional integrals are introduced. Mapping and semigroup properties, integral representations and Mellin transform analysis are presented. A relationship with the Riemann-Liouville fractional integrals is demonstrated. Finally, a second kind integral equation of the Volterra-type, involving the Laguerre fractional integral is solved in terms of the double hypergeometric type series as the resolvent kernel.
