Abstract

Consider an irreducible Markov chain which satisfies a ratio limit theorem, and let ρ be the spectral radius of the chain. We investigate the relation of the the ρ -Martin boundary with the boundary induced by the ρ -harmonic kernel which appears in the ratio limit. Special emphasis is on random walks on non-amenable groups, specifically, free groups and hyperbolic groups.
比率极限和马丁边界
考虑一个满足比值极限定理的不可约马尔可夫链,设ρ为链的谱半径。研究了ρ -Martin边界与比值极限中出现的ρ -调和核所诱导的边界的关系。特别强调非服从群的随机漫步,特别是自由群和双曲群。
