A past colloquim: people listening to a lecture at ImperialThe Departmental Colloquia series began in 2010. The purpose of the series is two fold: to hear from some of the world's leading mathematicians and statisticians, and to provide a forum for the department (faculty, research fellows, and postgraduate students) to meet.

There is usually a reception following the talk, with an opportunity to meet the speaker.

Upcoming Colloquia:

Title: Accelerated Simulation for Plasma Kinetics

Abstract: This presentation will discuss the kinetics of Coulomb collisions in plasmas, as described by the Landau-Fokker-Planck equation, and its numerical solution using a Direct Simulation Monte Carlo (DSMC) method. Acceleration of this method is achieved by coupling the particle method to a continuum fluid description. Efficiency of the resulting hybrid method is greatly increased by inclusion of particles with negative weights. This complicates the simulation, and introduces difficulties have plagued earlier efforts to use negatively weighted particles. This talk will describe significant progress that has been made in overcoming those difficulties.

The talk will be followed by reception in the Huxley Common Room (549)

Title: Counting Self-Avoiding Walks on a Lattice, from Combinatorics to Physics.

Abstract: A self-avoiding walk (SAW) on a graph is a path which does not visit any vertex twice. In this talk, we study an enumeration problem consisting in counting such walks of given lengths. More precisely, we will present the proof (obtained jointly with S. Smirnov) of a conjecture of Nienhuis stating that the number of SAWs of length non the hexagonal lattice grows like \sqrt{2+\sqrt 2}^{n+o(n)}. The proof will also shed new light on a very instructive and beautiful phase transition in the geometric properties of long SAWs.

The talk will be followed by reception in the Huxley Common Room (549)
