title = "On contour arguments for the three state Potts model with competing interactions on a semi-infinite Cayley tree",
abstract = "We consider the Potts model with competing two-step interactions and spin values 1, 2, 3 on a semi-infinite Cayley tree of order 2. We describe ground states and verify the Peierls condition for the model. Using a contour argument we show the existence of three different Gibbs measures associated with translation invariant ground states.",
