Abstract
In this thesis, we provide some existence and uniqueness results of solutions in Banach space, for nonlinear
mixed fractional differential equations (FDEs) with two different fractional derivatives and for nonlinear
fractional partial differential equations (FPDEs) involving the generalized Riesz–Caputo fractional derivative
(GRCFD) respectively, both with boundary conditions. We use the Banach's contraction principle, Schauder's
and Schaefer's fixed point theorems, and the technique of the nonlinear alternative of Leray-Schauder type.
We also derive the self-similar solutions in an explicit form of space-time fractional diffusion equation
involving Hilfer- Katugampola's fractional derivative (HKFD) by applying the successive approximation
method .
