Boundary asymptotics for two-dimensional vectorial Allen-Cahn systems

Zhiyuan Dai, Haotong Fu, Huaijie Wang +1

We study asymptotic properties of critical points of the two-dimensional vectorial Allen-Cahn energy with finitely many non-degenerate wells, subject to a homogeneous Neumann bound…

On the absence of point defects in biaxial Landau--de Gennes models

Haotong Fu, Huaijie Wang, Wei Wang +1

We study local minimizers of a sextic-potential Landau--de Gennes energy for nematic liquid crystals in the small-elastic-constant limit. Under the uniform energy and bo…

Improved convergence of Landau-de Gennes minimizers in the vanishing elasticity limit

Haotong Fu, Huaijie Wang, Wei Wang

We investigate the vanishing elasticity limit for minimizers of the Landau-de Gennes model with finite energy. By adopting a refined blow-up and covering analysis, we establish the…

Uniform estimates of Landau-de Gennes minimizers in the vanishing elasticity limit with line defects

Haotong Fu, Huaijie Wang, Wei Wang

For the Landau-de Gennes functional modeling nematic liquid crystals in dimension three, we prove that, if the energy is bounded by , then the seque…

Stratification and rectifiability of harmonic map flows via tangent measures

Haotong Fu, Wei Wang, Ke Wu +1

In this paper, we investigate the stratification theory for ``suitable solutions" of harmonic map flows based on the spatial symmetry of tangent measures. Building on the quantitat…
