Exact convergence rates of lightning plus polynomial approximation for branch singularities with uniform exponentially clustered poles

Shuhuang Xiang, Yanghao Wu, Shunfeng Yang

This paper builds rigorous analysis on the root-exponential convergence for the lightning schemes via rational functions in approximating corner (branch) singularity problems with…

math.NA2024

The root-exponential convergence of lightning plus polynomial approximation on corner domains

Shuhuang Xiang, Shunfeng Yang

This paper builds further rigorous analysis on the root-exponential convergence for lightning schemes approximating corner singularity problems. By utilizing Poisson summation form…

math.NA2023

On the best convergence rates of lightning plus polynomial approximations

Shuhuang Xiang, Shunfeng Yang, Yanghao Wu

Building on introducing exponentially clustered poles, Trefethen and his collaborators introduced lightning algorithms for approximating functions of singularities. These schemes m…
