Convolution quadrature for Hadamard fractional calculus and correction methods for the subdiffusion with singular source terms

Baoli Yin, Guoyu Zhang, Yang Liu +1

The convolution quadrature method originally developed for the Riemann-Liouville fractional calculus is extended in this work to the Hadamard fractional calculus by using the expon…

Sharp error analysis for averaging Crank-Nicolson schemes with corrections for subdiffusion with nonsmooth solutions

Baoli Yin, Yang Liu, Hong Li

Thanks to the singularity of the solution of linear subdiffusion problems, most time-stepping methods on uniform meshes can result in $O (τ)$ accuracy where $τ$ denotes the time ste…
