Abstract deformations of the CR structure of a compact strictly pseudoconvex hypersurface $M$ in $\mathbb{C}^2$ are encoded by complex functions on $M$. In sharp contrast with the higher dimensional case, the natural integrability condition for $3$-dimensional CR structures is vacuous, and generic deformations of a compact strictly pseudoconvex hypersurface $M\subseteq \mathbb{C}^2$ are not embeddable even in $\mathbb{C}^N$ for any $N$. A fundamental (and difficult) problem is to characterize… 
Obstruction flat rigidity of the CR 3-sphere
Abstract We consider the obstruction flatness problem for small deformations of the standard CR 3-sphere. That rigidity holds for the CR sphere was previously known (in all dimensions) for the case

Bounded strictly pseudoconvex domains in C2 with obstruction flat boundary
On a bounded strictly pseudoconvex domain in $\mathbb{C}^n$, $n>1$, the smoothness of the Cheng-Yau solution to Fefferman's complex Monge-Ampere equation up to the boundary is obstructed by a local
Embeddability for three-dimensional CR-manifolds
A question of principal interest in the theory of compact, three-dimensional CR-manifolds is to understand when a given strictly pseudoconvex, CR-structure can be realized by an embedding in C' . We

Embeddability for Three-Dimensional Cauchy-Riemann Manifolds and CR Yamabe Invariants
Let M^3 be a closed CR 3-manifold. In this paper we derive a Bochner formula for the Kohn Laplacian in which the pseudo-hermitian torsion plays no role. By means of this formula we show that the
EMBEDDED THREE-DIMENSIONAL CR MANIFOLDS AND THE NON-NEGATIVITY OF PANEITZ OPERATORS
Let ⊂ C 2 be a strictly pseudoconvex domain and M = @ be a smooth, compact and connected CR manifold embedded in C 2 with the CR structure induced from C 2 . The main result proved here is as
Nonnegativity of the CR Paneitz operator for embeddable CR manifolds
The non-negativity of the CR Paneitz operator plays a crucial role in three-dimensional CR geometry. In this paper, we prove this non-negativity for embeddable CR manifolds. This result and previous

A relative index on the space of embeddable CR-structures, I
We study the problem of embeddability for three dimensional CR-manifolds. Let (M, M0b) denote a compact, embeddable, strictly pseudoconvex CR-manifold and OS the orthogonal projection on ker 0&b. If
