Liquid Crystals from a Mathematical Persepective
ABSTRACT
Liquid crystals are materials whose properties are intermediate between normal fluids and solid crystal, and have widespread use as the working substance for computer, TV and watch displays. The lecture will give an introduction to these materials and what mathematics can say about them, and in particular discuss how different theories of liquid crystals describe orientational defects in different ways.
