Nearly optimal Kolmogorov widths under holomorphic mappings

Yuwen Li, Guozhi Zhang

This paper establishes essentially optimal asymptotic bounds for Kolmogorov widths under holomorphic mappings between complex Banach spaces. Given a compact parameter set whose Kol…

An Adaptive Finite Element Method Based on Generalized Barycentric Coordinates

Yihui Zhou, Yuwen Li

This work derives a posteriori error estimate of polygonal finite element methods based on Wachspress barycentric coordinates. In particular, we prove that the classical residual-b…

Improving accuracy of finite element solutions by smoothing

Yuwen Li, Han Shui, Ludmil Zikatanov

This paper develops a smoothing-based postprocessing method for improving the accuracy of finite element solutions. The method applies a few smoothing iterations, such as damped Ja…
