Abstract
We demonstrate the existence of a set of surfaces containing the director and related to each singularity (disclination, point disclination) of the director field. There can be as many sets as there are singularities. The normal to these surfaces defines a chiral axis at each point. A Burgers' circuit is introduced to measure the wedge component of the disclinationKeywords
