摘要

The volume density of a hyperbolic link K is defined to be the ratio of the hyperbolic volume of K to the crossing number of K. We show that there are sequences of non-alternating links with volume density approaching upsilon(oct), where upsilon(oct) is the volume of the ideal hyperbolic octahedron. We show that the set of volume densities is dense in [0, upsilon(oct)]. The determinant density of a link K is 2 pi log det(K)/c(K). We prove that the closure of the set of determinant densities contains the set [0, upsilon(oct)]. (C) 2016 Elsevier B.V. All rights reserved.
