Jiang, Yingjun; Ma, Jingtang High-order finite element methods for time-fractional partial differential equations. (English) Zbl 1216.65130 J. Comput. Appl. Math. 235, No. 11, 3285-3290 (2011). Summary: The aim of this paper is to develop high-order methods for solving time-fractional partial differential equations. The proposed high-order method is based on a high-order finite element method for space and a finite difference method for time. An optimal convergence rate of \(O((\Delta t)^{2 - \alpha }+N^{ - r})\) is proved for the \((r - 1)\)th-order finite element method (\(r\geq 2\)).
