The Chemical Potential of the Electron Gas on a Two-Dimensional Lattice
  The chemical potential of the electron gas on a two-dimensional recttangular lattice is determined.An approximate expression for exp(-mu/T) is obtained,and its second order approximation is discussed to some extent.This result will find applications in studies of high temperature superconductors and Q2D organic conductors.
