PDE/Analysis Seminar
SPECTRAL MULTIPLIERS FOR LAPLACIANS ASSOCIATED TO SOME DIRICHLET FORMS
Andrea Carbonaro
John Dedman Building, G35
Abstract
It has been conjectured that all the generators of symmetric diffusion semigroups have a bounded holomorphic functional calculus in Lp in the sector of angle $arcsin|2/p-1|,$ $1

Schramm-Loewner evolutions and counting self-avoiding walks.
Nathan Deutscher
John Dedman Building, G35
Abstract
The self-avoiding walk (SAW) is a notorious problem, yet like many statistical mechanics models it is now thought to have a Schramm-Loewner Evolution (SLE) as its continuum limit. This seminar introduces SLE and some results for the random curves it describes. The self-avoiding walk is discussed as one such curve with an additional restriction’ property that makes it easier to obtain the probability it avoids parts of the domain in which it walks. The link between SAWs, SLE and the restriction property enables the counting exponents to be calculated for walks confined to a wedge. These exponents describe how the number of SAWs with N steps within a wedge grows with N.

MSI Colloquium
Brown representability and model categories
Boris Chorny, ANU
John Dedman Building, G35
Abstract
I will introduce the concept of a model category and discuss some of its applications to various classification questions. No prior knowledge of Algebraic Topology will be assumed.
