Stability of the vortex defect in the Landau–de Gennes theory for nematic liquid crystals
[Stabilité du défaut vortex dans la théorie Landau–de Gennes pour les cristaux liquides]
Comptes Rendus. Mathématique, Tome 351 (2013) no. 13-14, pp. 533-537.

Nous étudions la solution à symétrie radiale associée au défaut de type vortex dans la théorie de Landau–de Gennes pour les cristaux liquides. Nous montrons des résultats dʼexistence, dʼunicité et de stabilité de cette solution.

We analyze the radially symmetric solution corresponding to the vortex defect (the so-called melting hedgehog) in the Landau–de Gennes theory for nematic liquid crystals. We prove the existence, uniqueness and stability results of the melting hedgehog.
