We embed compact $C^\infty$ manifolds into $\mathbb C^n$ as totally real manifolds with prescribed polynomial hulls. As a consequence we show that any compact $C^\infty$ manifold of dimension $d$ admits a totally real embedding into $\mathbb C^{\lfloor \frac{3d}{2}\rfloor}$ with non-trivial polynomial hull without complex structure. 

Polynomially convex embeddings of even-dimensional compact manifolds

We show that, for $k>1$, any $2k$-dimensional compact submanifold of $\mathbb{C}^{3k-1}$ can be perturbed to be polynomially convex and totally real except at a finite number of points. This lowers

Given a closed orientable abstract manifold M of odd dimension 2k +1, k ≥ 2, it is natural to look for the least n such that M can be embedded in C with certain prescribed properties. We recall that

Polynomial hulls of arcs and curves

It is shown that there exist arcs and simple closed curves in C 3 \mathbb {C}^3 with nontrivial polynomial hulls that contain no analytic discs. It is also shown that in any

The convergence of hulls of curves

We prove results about limits of simple closed curves and polynomial hulls. The results show, in particular, that the polynomially convex, rectifiable simple closed curves in Cn, n ≥ 2, form a dense

In the field of complex dynamics, the problem of classifying Fatou components for various classes of holomorphic maps is a major challenging open problem. It has been known that any non-recurrent

TLDR
It is shown that no purely topological condition implies the equality of the polynomial and rational hulls of a set: for any uncountable, compact subset of a Euclidean space, there exists a set that is rationally convex but not polynomially convex.

Polynomially convex embeddings of odd-dimensional closed manifolds

Abstract It is shown that any smooth closed orientable manifold of dimension 2⁢k+1{2k+1}, k≥2{k\geq 2}, admits a smooth polynomially convex embedding into ℂ3⁢k{\mathbb{C}^{3k}}. This improves by 1

In this paper it is shown that every compact two-dimensional manifold $S$, with or without boundary, can be embedded in $\mathbb C^3$ as a smooth submanifold $\Sigma$ in such a way that the

Optimality for totally real immersions and independent mappings of manifolds into C^N

The optimal target dimensions are determined for totally real immersions and for independent mappings into complex affine spaces. Our arguments are similar to those given by Forster, but we use

Holomorphic convexity and Carleman approximation by entire functions on Stein manifolds

We give necessary and sufficient conditions for totally real sets in Stein manifolds to admit Carleman approximation of class $${\mathcal C^k}$$, k ≥ 1, by entire functions.

Presence or absence of analytic structure in maximal ideal spaces

We study extensions of Wermer’s maximality theorem to several complex variables. We exhibit various smoothly embedded manifolds in complex Euclidean space whose hulls are non-trivial but contain no

Approximation by automorphisms on smooth submanifolds of Cn

We denote by AutC n the group of all holomorphic automorphisms of the complex Euclidean space C". This is a very large and complicated group when n > 2; tbr results in this direction see [5, 6, 11,
