Danny Calegari, Nathan M. Dunfield
We give an example of a subgroup of SL(2,C) which is a strictly ascending HNN extension of a non-abelian finitely generated free group F. In particular, we exhibit a free group F i…

Non-triviality of the A-polynomial for knots in S^3
Nathan M. Dunfield, Stavros Garoufalidis
The A-polynomial of a knot in S^3 defines a complex plane curve associated to the set of representations of the fundamental group of the knot exterior into SL(2,C). Here, we show t…
