Block splitting preconditioner for time-space fractional diffusion equations

Block splitting preconditioner for time-space fractional diffusion equations

For solving a block lower triangular Toeplitz linear system arising from the time-space fractional diffusion equations more effectively, a single-parameter two-step split iterative method (TSS) is introduced, its convergence theory is established and the corresponding preconditioner is also presente...
