余紧富克斯群上的随机游动

Random Walk on a Co-Compact Fuchsian Group

Sébastien Gouëzel, Steven P. Lalley

摘要:

证明了余紧富克斯群上对称有限值域随机游动的格林函数在收敛半径R处按距离指数衰减。还证明了安科纳不等式推广到R,因此R-势的马丁边界与自然几何边界S^1重合,马丁核是一致霍德尔连续的。最后,证明了这蕴含着转移概率的一个局部极限定理。

英文摘要:

It is proved that the Green's function of a symmetric finite range random walk on a co-compact Fuchsian group decays exponentially in distance at the radius of convergence R. It is also shown that Ancona's inequalities extend to R, and therefore that the Martin boundary for R-potentials coincides with the natural geometric boundary S^1, and that the Martin kernel is uniformly Hölder continuous. Finally, it is proved that this implies a local limit theorem for the transition probabilities.
