Remark on Existence and Uniqueness of Solutions for a Coupled System of Multiterm Nonlinear Fractional Differential Equations

Abstract

The aim of this paper is to extend the work of Sun et al. (2012) to a more general case for a wider range of function classes of $f$ and $g$. Our results include the case of the previous work, which are essential improvement of the work of Sun et al. (2012), especially.
