Nematic shells are the datum of a surface coated with a thin film of liquid crystals. Liquid crystals are composed by rod-shaped molecules, which tend to align to each other, locally. The interaction between the molecules and the surface induces topological defects, that is, regions of rapid changes in the orientation of the molecules that carry a topological charge. In this talk, we consider a (simplified) discrete model for nematic shells, where the molecules sit at the vertices of a triangular mesh, and study defects in the limit as the mesh parameter tend to zero. This is joint work with Antonio Segatti (Università di Pavia, Italy).
