本文考虑了一个具有V个顶点的完全图上N个玻色子通过硬核排斥相互作用的系统。利用动力学系统随机扰动的Ventsel ′-Freidlin大偏差理论，计算了热力学极限下的正则自由能，证明了系统存在相变。
We consider a system ofN bosons on a complete graph withV vertices interacting through hard core repulsion. With the use of the Ventsel'-Freidlin large-deviation theory of random perturbation of dynamical systems, we calculate the canonical free energy in the thermodynamic limit and prove that the system exhibits a phase transition.
