On a hyperbolic system arising in liquid crystals modeling
E. Feireisl, E. Rocca, G. Schimperna +1
We consider a model of liquid crystals, based on a nonlinear hyperbolic system of differential equations, that represents an inviscid version of the model proposed by Qian and Shen…
On a non-homogeneous eigenvalue problem involving a potential: an Orlicz-Sobolev space setting
Mihai Mihăilescu, Vicenţiu Rădulescu, Dušan Repovš
In this paper we study a non-homogeneous eigenvalue problem involving variable growth conditions and a potential . The problem is analyzed in the context of Orlicz-Sobolev space…
Liquid crystal defects in the Landau-de Gennes theory in two dimensions-beyond the one-constant approximation
Georgy Kitavtsev, Jonathan M Robbins, Valeriy Slastikov +1
We consider the two-dimensional Landau-de Gennes energy with several elastic constants, subject to general -radially symmetric boundary conditions. We show that for generic elas…
Existence results for variational-hemivariational problems with lack ofconvexity
Vicentiu Radulescu, Dušan Repovš
We establish existence results of Hartmann-Stampacchia type for a class of variational-hemivariationalinequalities on closed and convex sets (either bounded or unbounded) in a Hilb…
Combined effects in nonlinear problems arising in the study of anisotropic continuous media
Vicenţiu D. Rădulescu, Dušan D. Repovš
The paper deals with the study of a Lane-Emden-Fowler equation with Dirichlet boundary condition and variable potential functions. The analysis developed in this paper combines mon…
Stability of point defects of degree in a two-dimensional nematic liquid crystal model
Radu Ignat, Luc Nguyen, Valeriy Slastikov +1
We study -radially symmetric solutions corresponding to topological defects of charge for integer in the Landau-de Gennes model describing liquid crysta…
