Analytical solution of extended fractional space-time cable equation associated with Hilfer and Riemann-Liouville fractional derivatives

In this paper, we present a systematic investigation of a of the solution of generalized space-time fractional cable equation defined by (2.1) containing Riemann-Liouville and Hilfer fractional derivatives as the time  derivatives and  Riesz-Feller fractional derivative as the space derivative. The results are derived by the application of joint Laplace and Fourier transforms. The results are obtained in terms of the familiar H-function in a closed form. The moments of the solutions and their asymptotic behavior for small and large values of the argument are also obtained. The results are obtained in a compact form in terms of the Mittag-Leffler function and H-function. The results obtained by Can et al. [5] follow as special cases of our findings.
