Do we need decay-preserving error estimate for solving parabolic equations with initial singularity?

Jiwei Zhang, Zhimin Zhang, Chengchao Zhao

Solutions exhibiting weak initial singularities arise in various equations, including diffusion and subdiffusion equations. When employing the well-known L1 scheme to solve subdiff…

$α$ -robust error estimates of general non-uniform time-step numerical schemes for reaction-subdiffusion problems

Jiwei Zhang, Zhimin Zhang, Chengchao Zhao

Numerous error estimates have been carried out on various numerical schemes for subdiffusion equations. Unfortunately most error bounds suffer from a factor $1/ (1 - α)$ or $Γ (1 - α)$ ,…
