Abstract

New variable-order fractional differential equations are proposed and numerical solutions are given in this paper. Firstly, a new way is introduced to define variable--order functions. The initial conditions are varied on different intervals and the fractional differential equations hold short memory effects or short-term interactions. Existence results are provided by Banach fixed point theorem successively over different intervals. Finally, predictor corrector method is improved and numerical examples are illustrated accordingly.
