Growth of torsion Grigorchuk groups
Tianyi Zheng, Department of Mathematics, UC San Diego
On torsion Grigorchuk groups we construct random walks of finite entropy and power-law tail decay with non-trivial Poisson boundary. Such random walks provide near optimal volume lower estimates for these groups. Joint with Anna Erschler.
