Abstract
We study the core of line and point defects in nematic liquid crystals . The topological theory of defects allows us to prove that a uniaxial nematic has two ways to avoid a topologically stable defect: either i t melts, by becoming isotropic on the putative defect, or a complex bi axial structure arises, that we describe in the paper.
