ABSTRACT

In this contribution we discuss the occurrence of first-order transitions in temperature in various short-range lattice models with a rotation symmetry. Such transitions turn out to be widespread under the condition that the interaction potentials are sufficiently nonlinear.

Keywords: first-order transitions,order-disorder transitions,nonlinear vector models,liquid crystals,lattice gauge models
