我们研究了一类广泛的瞬态平面图,通过一个几何模型给出了一个正方形平铺的圆柱。对于许多图,平铺的几何边界是一个圆,并且易于一般地描述。图上的简单随机游动收敛(概率为1)到几何边界上的一个点。我们得到的信息的调和措施和估计的收敛速度。这使我们能够扩展结果,我们以前证明了三角形的磁盘。
We study a wide class of transient planar graphs, through a geometric model given by a square tiling of a cylinder. For many graphs, the geometric boundary of the tiling is a circle and is easy to describe in general. The simple random walk on the graph converges (with probability 1) to a point in the geometric boundary. We obtain information on the harmonic measure and estimates on the rate of convergence. This allows us to extend results we previously proved for triangulations of a disk.
