摘要
The structure of dispersed liquid crystal droplets is controlled by a balance of the bulk elasticity, surface tension, and surface anchoring. For sufficiently large droplets with radius R > K/W-a, where K is the bulk elastic constant and W-a is the anchoring coefficient, the surface terms prevail. As a result, the equilibrium states of large droplets contain topologically stable defects. Application of topological theorems to defect structures, e.g. monopoles, boojums and hedgehogs is reviewed.
