The L-zeta function of an infinite graph Y (defined previously in a ball around zero) has an analytic extension. For a tower of finite graphs covered by Y , the normalized zeta functions of the finite graphs converge to the L-zeta function of Y . Introduction Associated to any finite graph X there is a zeta function Z(X,u), u ∈ C. It is defined as an infinite product but shown (in various diffe...
