| Abstract: | We perform, analytically, the sum over the finite set of Matsubara frequencies that arises in the lattice thermodynamics of a free Fermi gas. The resultant expressions provide an easy demonstration that the correction continuum expressions are obtained in the limit of small lattice spacing. |
