Stein fillings of contact torus bundles
14.04.2015
Abstract: Torus bundles over the circle naturally arise as boundaries of
circular plumbings of spheres; when one of these spheres has positive
self-intersection, the boundary of the plumbing inherits a concave
contact structure. The aim of this talk is to classify Stein fillings of
a large family of these contact structures up to diffeomorphism. This is joint work with Paolo Lisca.
