| 520 | 3 | |a A high-order compact finite difference method is proposed for solving a class of time fractional convection-subdiffusion equations. The convection coefficient in the equation may be spatially variable, and the time fractional derivative is in the Caputo's sense with the order $$\alpha $$ α ( $$0<\alpha <1$$ 0 < α < 1 ). After a transformation of the original equation, the spatial derivative is discretized by a fourth-order compact finite difference method and the time fractional derivative is approximated by a $$(2-\alpha )$$ ( 2 - α ) -order implicit scheme. The local truncation error and the solvability of the method are discussed in detail. A rigorous theoretical analysis of the stability and convergence is carried out using the discrete energy method, and the optimal error estimates in the discrete $$H^{1}$$ H 1 , $$L^{2}$$ L 2 and $$L^{\infty }$$ L ∞ norms are obtained. Applications using several model problems give numerical results that demonstrate the effectiveness and the accuracy of this new method. | |
