正方形、三角形和六边形晶格上的非均匀键渗流

Inhomogeneous bond percolation on square, triangular and hexagonal lattices

Geoffrey R. Grimmett, Ioan Manolescu

摘要:

利用星三角变换得到了一个推广到正方形、三角形和六角晶格上的所有(不)均相键渗流模型的等价性。其中的后果是盒交叉(RSW)不等式的参数值的转换是有效的,这样的模型。这是向证明这些过程的普遍性和一致性迈出的一步。它蕴涵着这些值的临界性,从而为非均匀系统的临界点提供了一个新的证明。证明扩展到某些isoradial模型,以前的方法不适用。

英文摘要:

The star-triangle transformation is used to obtain an equivalence extending over the set of all (in)homogeneous bond percolation models on the square, triangular and hexagonal lattices. Among the consequences are box-crossing (RSW) inequalities for such models with parameter-values at which the transformation is valid. This is a step toward proving the universality and conformality of these processes. It implies criticality of such values, thereby providing a new proof of the critical point of inhomogeneous systems. The proofs extend to certain isoradial models to which previous methods do not apply.
