Query: Two-dimensional Gross-Neveu Model with Wilson Fermion Action at Finite
  Temperature and Density   We analytically investigate the 2-dimensional Gross-Neveu model at finite
temperature and density using Wilson fermion action. The relation between the
phase structure on the lattice and that in the continuum is clarified.
