摘要
In this paper, we consider translation-invariant Gibbs measures (TIGMs) for the HC-Blume-Capel model in case of "wands" with chemical potential with parameters (theta, eta) on the Cayley tree. It is proved that, for eta <= theta(3), there is a unique TIGM and, for eta > theta(3), there are exactly three TIGMs in the case of "wands" with chemical potential for the model under consideration. In addition, the problem of the (non)extremality of these measures is studied.
