Approximation of pseudohermitian structures via embeddings into spheres

Hendrik Herrmann, Chin-Yu Hsiao, Bernhard Lamel

Let $(X,T^{1,0}X)$ be a compact strictly pseudoconvex CR manifold which is CR embeddable into the complex Euclidean space. We show that $T^{1,0}X$ can be approximated in $\mathscr{…
