In this present work, the existence and uniqueness of solutions for fractional pantograph differential equations involving Riemann-Liouville and Caputo fractional derivatives are established by applying contraction mapping principle and Leray-Schauder’s alternative. The Mittag-Leffler-Ulam stability results are also obtained via generalized singular Gronwall’s inequality. Finally, we give an illustrative example.
