Abstract
This research paper deals with two novel varieties of boundary value problems for nonlinear hybrid fractional differential equations involving generalized fractional derivatives known as the Psi-Caputo fractional operators. Such operators are generated by iterating a local integral of a function with respect to another increasing positive function Psi. The existence results to the proposed systems are obtained by using Dhage's fixed point theorem. Two pertinent examples are provided to confirm the feasibility of the obtained results. Our presented results generate many special cases with respect to different values of a Psi function.
