摘要：

We have undertaken a theoretical study on the structure of planar solitons in nematic and smectic liquid crystals. In nematics we find a soliton solution which can be looked upon as an intertwine between two solitons. In a nematic obtained by unwinding a cholesteric and in a nematic with very high dielectric anisotropy, we have worked out energetics of solitons. A 2 pi soliton in a ferronematic or a smectic C becomes unstable due to the splay bend elastic anisotropy. The structures of pi solitons in smectic A and smectic C in the neighbourhood of a S-A-S-C phase transition have also been studied.
