分散液晶液滴的结构受体弹性、表面张力和表面锚定的平衡控制。对于半径为R>；K/W-a的足够大的液滴，其中K是体弹性常数，W-a是锚定系数，表面项占优势。因此，大液滴的平衡态包含拓扑稳定的缺陷。综述了拓扑定理在单极子、Boojum和Hedgehog等缺陷结构中的应用。
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.
