Pure Maths Colloquium: Aperiodic Tilings and Attractive Shapes
22 April 2013 16:00 in CM221
Aperiodic patterns and tilings - highly structured but
non-periodic decorations of Euclidean space - have proved a rich
source of mathematics at the interface of topology, geometry and
dynamics, as well as providing applications to mathematical
biology (viral models) and materials science (quasicrystals).
This talk, addressing just the mathematical point of view, will
introduce the subject for the non-specialist and describe some
recently developed tools drawn from topology, geometric group
theory and a little homological algebra, that have provided new
insights and made connections to the study of certain types of
chaotic attractors in manifolds.
