Deriving the Effective Polyakov Line Action for SU(3) Gauge Theories at Finite Density

I show how to use the "relative weights" method to extract the effective Polyakov line action corresponding
to SU(3) gauge theories, in particular pure-gauge, gauge-Higgs, and heavy quark theories.  For gauge fields 
coupled to matter at finite density, the application is to the sign problem.  There are several techniques to 
deal with the sign problem in the effective theory, and I will illustrate qualitative features of the solution 
using mean field methods.
