The Invariant Complex Structure on the Homogeneous Space Diff(S1)/Rot(S1)

Let Diff(S1) be the Frechet-Lie group of orientation preserving diffeomorphisms of the unit circle S1. Let Rot(S1) be the subgroup of metric preserving rotations. The homogeneous space M=Diff(S1)/Rot(S1) has a structure of a Frechet manifold. In this thesis, it is shown that on M there exists exactl...

Description
Summary:Let Diff(S1) be the Frechet-Lie group of orientation preserving diffeomorphisms of the unit circle S1. Let Rot(S1) be the subgroup of metric preserving rotations. The homogeneous space M=Diff(S1)/Rot(S1) has a structure of a Frechet manifold. In this thesis, it is shown that on M there exists exactly one complexe structure up to sign which is invariant under the action of Diff(S1) on M.
