Torsion in skein modules and shared knot surgeries

Efstratia Kalfagianni

For every $g > 0$ , we construct a closed Haken 3-manifold $M_{g}$ , whose only connected, incompressible surface is a non-separating surface of genus $g$ and discuss the torsion behavio…

On the quantum $sl_{3}$ invariant of positive links

Matthew Harper, Efstratia Kalfagianni

We use the skein theory of $sl_{3}$ -webs to study the properties of the quantum $sl_{3}$ -link polynomial of positive links. We give explicit formulae for the thre…

Seifert cobordisms and the Chen-Yang volume conjecture

Renaud Detcherry, Efstratia Kalfagianni, Shashini Marasinghe

We study the large $r$ asymptotic behavior of the Turaev-Viro invariants $T V_{r} (M; e^{\frac{2 π i}{r}})$ of 3-manifolds with toroidal boundary, under the operation of gluing a Seifert…

Skein modules and character varieties of Seifert manifolds

Renaud Detcherry, Efstratia Kalfagianni, Adam S. Sikora

We show that the Kauffman bracket skein module of a closed Seifert fibered 3-manifold $M$ is finitely generated over $Z [A^{\pm 1}]$ if and only if $M$ is irreducible and no…

Crossing numbers of cable knots

Efstratia Kalfagianni, Rob Mcconkey

We use the degree of the colored Jones knot polynomials to show that the crossing number of a $(p, q)$ -cable of an adequate knot with crossing number $c$ is larger than $q^{2} c$ . A…
