摘要
The work is devoted to gradient Gibbs measures (GGMs) of an SOS model with countable set Z of spin values and having alternating magnetism on Cayley trees. This model is defined by a nearest-neighbour gradient interaction potential. Using Kulske-Schriever argument, based on boundary law equations, we give several q-height-periodic translations invariant GGMs for q = 2, 3, 4.
