Stability of point defects of degree $\pm \frac{1}{2}$ in a two-dimensional nematic liquid crystal model

Radu Ignat, Luc Nguyen, Valeriy Slastikov +1

We study $k$-radially symmetric solutions corresponding to topological defects of charge $\frac{k}{2}$ for integer $k\ne 0$ in the Landau-de Gennes model describing liquid crysta…
