Fractional and operational calculus with generalized fractional derivative operators and Mittag-Leffler type functions

摘要

In this paper, we study a certain family of generalized Riemann-Liouville fractional derivative operators of order α and type β, which were introduced and investigated in several earlier works [R. Hilfer (ed.), Applications of Fractional Calculus in Physics, World Scientific Publishing Company, Singapore, New Jersey, London and Hong Kong, 2000; R. Hilfer, Fractional time evolution, in Applications of Fractional Calculus in Physics, R.

In particular, we derive various compositional properties, which are associated with Mittag-Leffler functions and Hardy-type inequalities for the generalized fractional derivative operator . Furthermore, by using the Laplace transformation methods, we provide solutions of many different classes of fractional differential equations with constant and variable coefficients and some general Volterra-type differintegral equations in the space of Lebesgue integrable functions. Particular cases of these general solutions and a brief discussion about some recently investigated fractional kinetic equations are also given.View full textDownload full textKeywordsRiemann-Liouville fractional derivative operator, generalized Mittag-Leffler function, Hardy-type inequalities, Laplace transform method, Volterra differintegral equations, fractional differential equations, fractional kinetic equations, Lebesgue integrable functions, Fox-Wright hypergeometric functions 2000 Mathematics Subject Classification Primary: 26A33, 33C20, 33E12, Secondary: 47B38, 47G10Related var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10652461003675737
