A complex-analytic characterization of Lagrangian immersions in $C^{n}$ with transverse double points

Purvi Gupta, Rudranil Sahu

Given a compact smooth totally real immersed $n$ -submanifold $M \subset C^{n}$ with only finitely many transverse double points, it is known that if $M$ is Lagrangian with resp…

Polynomially convex embeddings and CR singularities of real manifolds

Purvi Gupta, Rasul Shafikov

It is proved that any smooth manifold $M$ of dimension $m$ admits a smooth polynomially convex embedding into $C^{n}$ when $n \geq ⌊ 5 m /4 ⌋$ . Further, such…
