TOPIC | Ergodic Theory and Dynamical Systems SeminarㅣZeta function of graphs of groups from cuspidal tree-lattices | ||
소개 및 안내사항Content | Abstract: We investigate the behavior of zeta functions of infinite graphs of groups which are quotients of cuspidal tree-lattices. This includes every non-uniform arithmetic quotients of the tree of $PGL_2$ over local fields. Several examples of zeta functions are provided. In particular, we give pairs of non-isomorphic cuspidal tree-lattices which have the same Ihara zeta function. We also discuss the spectral behavior of a sequence of graphs of groups constructed in Efrat (1990) in a zeta function point of view. https://us02web.zoom.us/j/82314084603?pwd=emxpTXorVHRieERoRnovNTNTOTNGUT09 ID: 823 1408 4603 PW: setds22 |
