We address the problem of existence and uniqueness of a Levi-flat hypersurface $M$ in $C^n$ with prescribed compact boundary $S$ for $n\ge3$. The situation for $n\ge3$ differs sharply from the well studied case $n=2$. We first establish necessary conditions on $S$ at both complex and CR points, needed for the existence of $M$. All CR points have to be nonminimal and all complex points have to be "flat". Then, adding a positivity condition at complex points, which is similar to the ellipticity… 
Boundary problem for Levi flat graphs
In an earlier paper the authors provided general conditions on a real codimension 2 submanifold $S\subset C^{n}$, $n\ge 3$, such that there exists a possibly singular Levi-flat hypersurface $M$
Some results on evolution
Let $K$ be a compact subset of $\mathbb C^n$, $K^\ast K$ a closed subset. In this paper we are dealing with evolution $E_t(K,K^\ast)$ of $K$ with fixed part $K^\ast$ by Levi form. This amounts to
Flattening of CR singular points and analyticity of the local hull of holomorphy I
This is the first article of the two papers in which we investigate the holomorphic and formal flattening problem for a codimension two real submanifold in $${\mathbb C}^n$$Cn with $$n\ge 3$$n≥3 near
Boundaries of Levi-flat hypersurfaces: special hyperbolic points
Let $S\subset \C^n$, $n\geq 3$ be a compact connected 2-codimensional submanifold having the following property: there exists a Levi-flat hypersurface whose boundary is $S$, possibly as a current.
Flattening a non-degenerate CR singular point of real codimension two
This paper continues the previous studies in two papers of Huang–Yin [HY16,HY17] on the flattening problem of a CR singular point of real codimension two sitting in a submanifold in $${{\mathbb
Real submanifolds in complex spaces
Let (z11,..., z1N,..., zm1,..., zmN, w11,..., wmm) be the coordinates in $${\mathbb{C}^{mN + {m^2}}}$$ℂmN+m2. In this note we prove the analogue of the Theorem of Moser in the case of the

The purpose of this paper is to generalize in a geometric setting theorems of Severi, Brown and Bochner about analytic continuation of real analytic functions which are holomorphic or harmonic with
A note on a family of analytic discs attached to a real submanifold M ⊂ C N + 1 with a CR singularity
In this note we construct a family of analytic discs attached to a real submanifold M ⊂ CN+1 of codimension 2 with a CR singularity. These discs are mutually disjoint and form a smooth hypersurface
Geometric and analytic problems for a real submanifold in ℂn with CR singularities
In this survey article, we present some known results and also propose some open questions related to the analytic and geometric aspects of Bishop submanifolds in a complex space. We mainly focus on
On Complex Points of Codimension 2 Submanifolds
In this paper we study the structure of complex points of codimension 2 real submanifolds in complex $$n$$n-dimensional manifolds. We show that the local structure of complex points up to isotopy


Extension of Levi-flat hypersurfaces past CR boundaries
Local conditions on boundaries of C∞ Levi-flat hypersurfaces, in case the boundary is a generic submanifold, are studied. For nontrivial real analytic boundaries we get an extension and uniqueness
CR Analytic Varieties with Given Boundary
Let us recall the Hartogs-Bochner-Martinelli theorem: let Ω be a bounded open set in ℂ n (n ≥ 2), with smooth connected boundary ∂Ω, and let f be a smooth CR function on ∂Ω. Then there exists F ∈
It is shown that, if a generating manifold does not contain proper submanifolds of the same CR dimension as , then all CR functions can be extended from into some wedge with edge . In particular,
