Abstract
Energetic stability of loop defects in nematic liquid crystal is analy sed using Mori-Nakanishi ansatz and Frank-Oseen theory with non-sere K -24 divergence term. The ratio of the bulk and divergence elastic cons tants defines a characteristic material length, which is the equilibri um radius a of the disclination ring. Positive K-24 forces the ring t o shrink.
