Strong solutions for the Beris-Edwards model for nematic liquid crystals with homogeneous Dirichlet boundary conditions. (English) Zbl 1333.35174

Summary: Existence and uniqueness of local strong solutions for the Beris-Edwards model for nematic liquid crystals, which couples the Navier-Stokes equations with an evolution equation for the \(Q\)-tensor, is established on a bounded domain \(\Omega \subset \mathbb{R}^d\) in the case of homogeneous Dirichlet boundary conditions. The classical Beris-Edwards model is enriched by including a dependence of the fluid viscosity on the \(Q\)-tensor. The proof is based on a linearization of the system and Banach’s fixed-point theorem.
