The 1st Joint Scientific Congress of the CMOS, CGU and CWRA will take place from May 26th to 30th 2013 at Teacher's Credit Union Place in Saskatoon, Saskatchewan. A joint Scientific Program Committee has already been formed to organize the sessions...

Abstract There has been striking progress on the theory of Hamiltonian partial differential equations over the past two decades. This talk will survey some of the definitive results and highlight remaining mysteries for future study.

Abstract: The nonlinear Kompaneets (NLK) equation describes the spectra of photons interacting with a rarefied electron gas. We exhibit five previously unknown classes of explicit time-dependent solutions (each class depending on initial conditions...

Abstract: In the 1830s Henry Fox Talbot discovered a self-imaging phenomenon in coherent illumination of a periodic diffraction grating. Since then, studies of the Talbot effect (as it is called) have themselves recurred frequently. One such...

Abstract: This is a study of the Euler equations for free surface water waves in the case of varying bathymetry, considering the problem in the shallow water scaling regime. In the case of rapidly varying periodic bottom, this is a problem of...

Abstract: Relics of early life, preceding even the last universal common ancestor of all life on Earth, are present in the structure of the modern day canonical genetic code. In this talk, I will draw attention to these relics, and discuss their...

Chern-Simons theory, as introduced by Witten, is a three dimensional quantum gauge theory associated to a compact simple Lie group and a level. The mathematical model of this theory as a topological quantum field theory was introduced by Reshetikhin...

I will give an overview of a few places where combinatorial structures have an interesting role to play in quantum field theory and which I have been involved in to varying degrees, from the Connes-Kreimer Hopf algebra and other renormalization Hopf...
