00pm, April 21st The renormalization group (RG) relates physics at different scales. Its initial success has been in studying problems associated with divergence and running coupling constants in relativistic quantum field theory (QFT). One famous and wellaccepted triumph of RG is the discovery of asymptotic freedom in nonAbelian gauge theories, which constitutes the foundation of quantum chromodynamics. In the last thirty years, the RG has found applications in many branches of physics, including critical phenomena in statistical physics, nonequilibrium systems such as turbulent fluids, and polymer physics, etc. Mathematical foundation of RG is still lacking and there are progress made by mathematical physicists. Recently, the
RG theory formulated by Wilson has been generalized to describe more general
extended singularities. This new RG frontier will be presented by Prof.
Rivasseau, a leading mathematical physicist in constructive QFT, emphasizing
on its application to twodimensional interacting Fermi liquids which
attracted much research recently primarily due to its intimate relationship
with high temperature superconductivity. To help the audiences to understand
RG, a brief review on RG will be given by Prof. Rivasseau in the first
two lectures.
