摘要: In this talk, we consider the nematic liquid crystal flow (NLCF) which couples strongly the forced Navier-Stokes equation and the transported harmonic map heat flow in two dimensions. We shall study how finite-time singularities form in (NLCF) with different boundary conditions. Interior bubbling phenomenon will be shown in the Dirichlet case, while both interior and boundary bubbling phenomena will be investigated for (NLCF) with partially free boundary. This talk is based on joint works with C.-C. Lai, F. Lin, Y. Sire, C. Wang and J. Wei.
