标记构形空间上的Gibbs测度:存在性与唯一性

Gibbs Measures on Marked Configuration Spaces: Existence and Uniqueness

Diana Conache, Alexei Daletskii, Yuri Kondratiev, Tanja Pasurek

摘要:

研究了欧氏空间中相互作用粒子无限系统的平衡态。这些粒子带有“无界”自旋,具有给定的对称先验分布。粒子之间的相互作用是成对的,并分为位置-位置和自旋-自旋部分。位置-位置部分由超稳势描述,自旋-自旋部分是吸引的,且是有限范围的。系统的热力学状态被定义为标记配置空间上的回火吉布斯测度。我们得到了这些吉布斯测度存在唯一的充分条件。

英文摘要:

We study equilibrium states of an infinite system of interacting particles in a Euclidean space. The particles bear `unbounded' spins with a given symmetric a priori distribution. The interaction between the particles is pairwise and splits into position-position and spin-spin parts. The position-position part is described by a superstable potential, and the spin-spin part is attractive and of finite range. Thermodynamic states of the system are defined as tempered Gibbs measures on the space of marked configurations. We derive sufficient conditions of the existence and uniqueness of these Gibbs measures.
