Legendrian knot invariants in Seifert fibered spaces

Knot theory beyond the three-sphere has seen increased attention in recent years, and in this talk I'll focus on knot theory in Seifert fibered spaces. In particular, we'll consider Legendrian knots in Seifert fibered spaces equipped with a special contact form. This setting gives rise to both topological and contact geometric questions, and I'll describe some of the ingredients used to prove the Legendrian non-simplicity of an infinite family of knot types representing torsion homology classes. This is joint work with J. Sabloff.
