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.
