The space of Cauchy-Riemann structures on 3-D compact contact manifolds
John Bland, Tom Duchamp
We study the action of the group of contact diffeomorphisms on CR deformations of compact three-dimensional CR manifolds. Using anisotropic function spaces and an anisotropic struc…

The Group of Contact Diffeomorphisms for Compact Contact Manifolds
John Bland, Tom Duchamp
For a compact contact manifold it is shown that the anisotropic Folland-Stein function spaces form an algebra. The notion of anisotropic regularity is extended to define the space…

Singular Monge-Ampere foliations
Tom Duchamp, Morris Kalka
This replaces the previous version, by correcting an error in the proof of Theorem 1.4, that was pointed out by the referee.
