可数群的sofic近似是有限集合上的部分作用序列,它通过左平移渐近地近似群对自身的作用。一个群是sofic的,如果它容许sofic近似。索菲熵理论是动力学中经典熵理论对索菲群作用的推广。然而,一个动作的sofic熵可能取决于sofic近似的选择。所有先前已知的例子表明这种依赖于退化行为。本文给出了具有两个不同正熵的有限型混合子移位的一个显式例子。这个例子的灵感来自于统计物理学文献中关于随机超图的2-着色。引用
A sofic approximation to a countable group is a sequence of partial actions on finite sets that asymptotically approximates the action of the group on itself by left-translations. A group is sofic if it admits a sofic approximation. Sofic entropy theory is a generalization of classical entropy theory in dynamics to actions by sofic groups. However, the sofic entropy of an action may depend on a choice of sofic approximation. All previously known examples showing this dependence rely on degenerate behavior. This paper exhibits an explicit example of a mixing subshift of finite type with two different positive sofic entropies. The example is inspired by statistical physics literature on 2-colorings of random hyper-graphs. References
