Contact embeddings in three dimensions

Olguta Buse (Indiana University-Purdue University Indianapolis )

Abstract: We study neighborhoods of transversal knots in contact thee dimensional manifolds. By doing so, we introduce the concepts of capacity and shape for a three dimensional contact manifold $(M, \xi)$ relative to a transversal knot $K$. We will explain the connection with the existing literature and provide our main computation for the shape in the case of lens spaces $L(p,q)$ with a toric contact structure. The main tool used here are rational surgeries which will be explained through their toric interpretations based on the continuous fraction expansions of $p/q$. This is joint work with D. Gay.

Embedding of Heisenberg group in L_1

Jeremy and Chris (UIUC)

Abstract: This is an introduction to a series of lectures showing that the Heisenberg group does not embed in (commutative) L_1
