Title: Embedded contact homology of circle bundles

Place: Seminar Room A
Abstract: Embedded contact homology is a topological invariant of three-manifolds (due to Hutchings), defined by choosing a contact structure on a three-manifold and studying pseudoholomorphic curves in its (four-dimensional) symplectization. It provides a link between Seiberg-Witten gauge theory and contact geometry. We compute this invariant for nontrivial circle bundles over Riemann surfaces (prequantization spaces).
