On stability of radial hedgehog in Landau - de Gennes model

Tuesday 9th April 2013 - 11:30 to 12:30
We investigate stability of radially symmetric solutions in the context of Landau - de Gennes theory. It is well known that radial hedgehog is an unstable solution for low enough temperatures. We show that radial hedgehog is locally stable solution for temperatures close to isotropic-nematic phase transition temperature.
