Title: Reeb Dynamics and Topological Decompositions

Abstract: a contact form on a three-manifold determines a 
foliation by one-manifolds called Reeb orbits, and these 
are the building blocks for a family of contact invariants 
coming from symplectic field theory.  Recent efforts to 
model these invariants topologically suggest the following 
question: given a decomposition of a three-manifold M into 
one-manifolds, is there a contact form on M whose Reeb 
orbits realize the decomposition? This talk will discuss 
related obstructions, necessary conditions, and open 
questions, as well as introducing the topological 
invariants which motivate the topic.
