Abstract

In this article, we develop an invariant subspace method for a system of time-fractional nonlinear partial differential equations in \((1+2)\) dimensions. Efficacy of the method is demonstrated by solving coupled system of nonlinear time-fractional diffusion equations and coupled system of time-fractional Burger’s equations in higher dimensions. Furthermore, the algorithmic approach to find more than one invariant subspace is proposed and corresponding exact solutions are constructed.
