Automorphism groups of normal CR 3-manifolds

Differential Geometry 2007-05-23 v2

Abstract

We classify the normal CR structures on S3S^3 and their automorphism groups. Together with [3], this closes the classification of normal CR structures on contact 3-manifolds. We give a criterion to compare 2 normal CR structures, and we show that the underlying contact structure is, up to homotopy, unique.
