Deformation Theory for the Hyperplane Line Bundle on $P^{1}$

John Bland and Thomas Duchamp

Full-text: Open access


We develop a correspondence between deformations of the standard CR structure on $S^3$ and deformations of formal neighbourhoods of the hyperplane bundle over ${\mathbb{P}}^1$; this correspondence leads to a geometric description of obstructions to the embeddability of CR structures.
