Existence results for a multipoint boundary value problem of nonlinear sequential hadamard fractional differential equations

Abstract

In this paper, existence and uniqueness results are estab-lished for a nonlinear sequential Hadamard fractional differential equation with multi-point boundary conditions, via Banach and Krasnosel’skiĭ’s fixed point theorems and Leray-Schauder nonlinear alternative. An example illustrating the existence of a unique solution is also constructed.
