Abstract

One solution describing an antiferroelectric liquid crystal in a finite sample having the helical structure in the centre and unwound at surfaces is proposed. This solution is composed of twist-edge dispirations. Their elastic interaction energy is estimated and used to determine static equilibrium dispiration positions. Another solution is the system of the 2π-twist disclinations in antiferroelectric liquid crystals. Both solutions can play the same role as 2π-twist disclinations in ferroelectric liquid crystals. Which solution occurs depends on material constants.
