Abstract: We study the Knieper measures of the geodesic flows on non-compact rank 1 manifolds of non-positive curvature. We construct the Busemann density on the ideal boundary, and prove that if there is a Knieper measure…

Abstract: Let x be a complex number which has a positive real part, and w_1,...,w_N be positive rational numbers. We write w^s \zeta_N (s, x | w_1,...,w_N) as a finite linear combination of the Hurwitz zeta…
