Numerical Investigation of Single-Core to Split-Core Transitions in Nematic Liquid Crystals
Daniel Siebel-Cortopassi, Pei Liu
We analyze single-core and split-core defect structures in nematic liquid crystals within the Landau-de Gennes framework by studying minimizers of the associated energy functional.…

Asymptotic Error Analysis of Gauss Quadrature for Nonsmooth Functions
Pei Liu
We derive an asymptotic error formula for Gauss--Legendre quadrature applied to functions with limited regularity, using the contour-integral representation of the remainder term.…

On a class of non-integer dimensional continuous functions with one unbounded variation point
Pei-Zhi Liu, Yong-Shun Liang, Jun-Ru Wu
This paper constructs a class of non-integer dimensional continuous functions with one unbounded variation point, discusses their Hölder condition and variation on their domains.…
