The Ising lattice with Brascamp-Kunz boundary conditions and an external magnetic field
The partition function of the finite Ising lattice with Brascamp-Kunz boundary conditions is calculated exactly in the absence of an external magnetic field and for an external field iπ/2.

The free energy of the non-isotropic Ising lattice with Brascamp-Kunz boundary conditions
The free energy of the finite and non-isotropic Ising lattice with Brascamp-Kunz boundary conditions is calculated exactly as a series in the absence of an external magnetic field.
