On links with cyclotomic Jones polynomials

Abhijit Champanerkar and Ilya Kofman

Algebraic & Geometric Topology 6 (2006) 1655–1668

arXiv: math.GT/0605631

Abstract

We show that if {Ln} is any infinite sequence of links with twist number τ(Ln) and with cyclotomic Jones polynomials of increasing span, then limsupτ(Ln) = . This implies that any infinite sequence of prime alternating links with cyclotomic Jones polynomials must have unbounded hyperbolic volume. The main tool is the multivariable twist–bracket polynomial, which generalizes the Kauffman bracket to link diagrams with open twist sites.

Keywords
