Method of the sublattice previously introduced for homogeneous lattices is adapted here to characterize ground state properties of two inhomogeneous lattices: Kagomà e lattice with coordination 4 and Five-points-star lattice with coordination 5. A representative cell must be chosen in each case in s

We modify the usual isotropic ±J Ising spin glass model introducing stronger interactions by a factor of f (anisotropy factor) along one of the axis. We begin by considering the situation in which concentration of ferromagnetic (F) and antiferromagnetic (AF) interactions are the same, where we study
For a d-dimensional 4' lattice field theory consisting of N spins, an asymptotic expansion of expectations about the Ising limit is established in inverse powers of the bare coupling constant A. In the thermodynamic limit (N -+ co), the expansion is expected to be valid in the noncritical region of
