Liquid crystals from a mathematical perspective

Event Start

Building 1,Level 4, Room 4102


Liquid crystals are materials whose properties are intermediate between normal fluids and solid crystals and have widespread use as the working substance for computers, TV, and watch displays. The lecture will introduce 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.
