Abstract:
We examine the $p$-adic hard-core model with three states on a Cayley tree. Translationinvariant and periodic $p$-adic Gibbs measures are studied for the hard-core model for $k=2$. We prove that every $p$-adic Gibbs measure is bounded for $p\ne2$. We show in particular that there is no strong phased transition for a hard-core model on a Cayley tree of order $k$.
