The conference/minisymposia will bring together researchers with a common interest in combinatorial modelling of natural phenomena in biology, chemistry and physics. Areas of application will include: models of DNA/RNA, phase transitions, material...

The Applied Combinatorics summer school is a two week program of minicourses and exploration sessions. It is designed to give students state of the art knowledge of combinatorial techniques and open problems in physics, chemistry and biology. The...

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...
