不变单调耦合不需要存在
Invariant monotone coupling need not exist
摘要:
我们通过例子表明,有一个凯莱图,有两个不变的随机子图X和Y,使它们之间存在单调耦合的意义,$X\subset Y$,虽然没有这样的耦合可以是不变的。这里,“不变”意味着分布在群乘法下是不变的。
英文摘要:
We show by example that there is a Cayley graph, having two invariant random subgraphs X and Y, such that there exists a monotone coupling between them in the sense that $X\subset Y$, although no such coupling can be invariant. Here, "invariant" means that the distribution is invariant under group multiplications.
