Knot traces and concordance

A conjecture of Akbulut and Kirby from 1978 states that the concordance class of a knot is determined by its 0-surgery.

Embedding problems in affine algebraic geometry and slice knots

We first discuss classical questions about polynomial embeddings of the complex line C into complex spaces such as C^m and affine algebraic groups. Next, we consider knots and different notions of sliceness for knots.

Free Seifert fibered pieces of pseudo-Anosov flows

We prove a structure theorem for pseudo-Anosov flows restricted to Seifert fibered pieces of three manifolds. The piece is called periodic if there is a Seifert fibration so that a regular fiber is freely homotopic, up to powers, to a closed orbit of the flow.
