Özet

This paper focuses on revisiting and improving the results regarding the existence of a solution to the implicit fractional differential equations (FDEs) given in the following form: (Formula presented.) for all (Formula presented.) with the initial condition (Formula presented.), where (Formula presented.) is the Caputo fractional derivative (CFD). Mainly, we aim to weaken the necessary conditions often found in the literature for guaranteeing the existence of solution.
