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 the previously known lower bound of 3⁢k+1{3k+1} on the possible ambient complex dimension for such embeddings (which is sharp when k=1{k=1}). It is further shown that the embeddings produced have the property that all continuous functions on the image can be uniformly approximated by holomorphic…

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
Polynomial convexity and totally real manifolds
In this article we study generic properties of totally real submanifolds M of . On the one hand we show that if M is polynomially convex and also has bounded exhaustion hulls, then sufficiently small
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,
Complex Stiefel Manifolds, some homotopy groups and vector fields
Introduction. Throughout this note M will denote a 6, closed, compact, connected, 2^-dimensional, almost-complex manifold. That is, M is an orientable manifold and there is a reduction of the
Unfolding CR Singularities
A notion of unfolding, or multi-parameter deformation, of CR singularities of real submanifolds in complex manifolds is proposed, along with a definition of equivalence of unfoldings under the action

Totally real embeddings with prescribed polynomial hulls
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 $d$
Some applications of the Stone-Weierstrass theorem to planar rational approximation
The Stone-Weierstrass theorem is used to prove two general results about algebras of continuous functions, and each of these yields a necessary and sufficient condition for the planar function
