Fyrirlesari: Gordon Slade (University of British Columbia)Titill: Self-avoiding walk, spin systems, and renormalisationÁgrip: The subject of critical phenomena in statistical mechanics is a rich source of interesting and difficult mathematical problems that touch oncombinatorics, probability, and mathematical physics. Self-avoiding walks and lattice spin systems provide fundamental examples. This talkwill address recent progress in computing critical exponents for these models, using a rigorous version of Wilson’s renormalisation group method.
