The Kauffman bracket skein module of a twist knot exterior

open access: yes, 2004
We compute the Kauffman bracket skein module of the complement of a twist knot, finding that it is free and infinite dimensional. The basis consists of cables of a two-component link, one component of which is a meridian of the knot.

A generalization of Vassiliev's planarity criterion [PDF]

open access: yes, 2012
Motivated by his studies in knot theory V. Vassiliev introduced $X$-graphs as regular 4-valent graph with a structure of pairs of opposite edges at each vertex.

A diagrammatic Alexander invariant of tangles

open access: yes, 2012
We give a new construction of the one-variable Alexander polynomial of an oriented knot or link, and show that it generalizes to a vector valued invariant of oriented tangles.Comment: 8 ...

Ordering the Reidemeister moves of a classical knot

open access: yes, 2009
We show that any two diagrams of the same knot or link are connected by a sequence of Reidemeister moves which are sorted by type.Comment: This is the version published by Algebraic & Geometric Topology on 18 May ...

Connect sum and transversely non simple knots

open access: yes, 2008
We prove that transversal non-simplicity is preserved under taking connect sum, generalizing Vertesi's result.Comment: Following the referee, exposition is changed and misprints are ...

Boundary slopes (nearly) bound cyclic slopes

open access: yes, 2004
Let r_m and r_M be the least and greatest finite boundary slopes of a hyperbolic knot K in S^3. We show that any cyclic surgery slopes of K must lie in the interval (r_m - 1/2, r_M + 1/2).Comment: Published by Algebraic and Geometric Topology at http://

Orientable closed 3-manifolds with surface-complexity one

open access: yes, 2010
After a short summary of known results on surface-complexity of closed 3-manifolds, we will classify all closed orientable 3-manifolds with surface-complexity one.Comment: 9 pages, 3 figures, 1 table; minor changes: appendix on a theorem stated in ...
