Galois coverings of Schreier graphs of groups generated by bounded automata. (arXiv:1711.03432v1 [math.CO])

来源于:arXiv
We give a characterization of the covering Schreier graphs of groups generated by bounded automata to be Galois. We also investigate the zeta and $L$ functions of Schreier graphs of few groups namely the Grigorchuk group, Gupta-Sidki $p$ group, Gupta-Fabrykowski group and BSV torsion-free group. 查看全文>>
