DESCRIPTION:Lines of large-N conformal fixed points with and without super
 symmetry are plentiful in three dimensions\, thanks in part to the quantiz
 ation of the Chern-Simons level k. Such theories are interesting for a var
 iety of reasons\, most importantly for their potential role as holographic
  dual descriptions of quantum theories of gravity in AdS4. In this talk\, 
 we will study a particularly simple and instructive non-supersymmetric exa
 mple  --  U(N) Chern-Simons theory coupled to fundamental fermions. As we 
 shall illustrate by calculating the free energy of the theory on R2 at fin
 ite temperature for all values of the 't Hooft coupling lambda=N/k\, this 
 theory turns out to be surprisingly tractable in the large-N limit.\n\n
