Abstracts		Professor Charles Radin University of Texas, at Austin 28 October 2013, at 15:30 Benjamin Auditorium (Sego 1), Sego Architecture Building Technion 29, 31 October 2013, at 15:30 Auditorium 231, Amado Mathematics Building Technion Charles Radin is a Professor of Mathematics at the University of Texas at Austin, and a Fellow of the American Mathematical Society. He is well-known for his fundamental work on packings, tilings, dynamics and mathematical physics. His research interests include Hilbert's eighteenth problem - understanding the symmetry of optimally dense packings, of spheres or polyhedra, in Euclidean and hyperbolic spaces, including aperiodic tilings such as the pinwheel tiling and the Penrose tiling. He is also interested in the closely related physics problem of the origin of structure in high density/low energy matter, which he studies using probabilistic models of spheres packing. Another topic he is interested in is phase transitions in various exotic materials in and out of thermal equilibrium, for instance soft matter such as sand piles, as well as quasicrystals. He has recently been applying similar ideas to random networks and graph theory.
