On Lewy extension for smooth hypersurfaces in ${\mathbb{C}}^n\times \mathbb{R}$

Jiri Lebl, Alan Noell, Sivaguru Ravisankar

We prove an analogue of the Lewy extension theorem for a real dimension $2n$ smooth submanifold $M\subset {\mathbb{C}}^n\times \mathbb{R}$, $n\ge 2$. A theorem of Hill and Tai…
