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 $M$ bounded by $S$. In this paper we consider the case when $S$ is a graph of a smooth function over the boundary of a bounded strongly convex domain $\Omega\subset C^{n-1}\times R$ and show that in this case $M$ is necessarily a graph of a smooth function over $\Omega$. In particular, $M$ is non-singular. 
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.
On the Levi-flat Plateau problem
We solve the Levi-flat Plateau problem in the following case. Let $$M \subset {\mathbb {C}}^{n+1}$$ M ⊂ C n + 1 , $$n \ge 2$$ n ≥ 2 , be a connected compact real-analytic codimension-two submanifold
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 $${{\mathbb
Codimension Two CR Singular Submanifolds and Extensions of CR Functions
Let $$M \subset {\mathbb {C}}^{n+1}$$M⊂Cn+1, $$n \ge 2$$n≥2, be a real codimension two CR singular real analytic submanifold that is nondegenerate and holomorphically flat. We prove that every real
Flattening of CR singular points and analyticity of the local hull of holomorphy I
This is the first article of the two papers in which we investigate the holomorphic and formal flattening problem for a codimension two real submanifold in $${\mathbb C}^n$$Cn with $$n\ge 3$$n≥3 near
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
A CR singular analogue of Severi’s theorem
Real-analytic CR functions on real-analytic CR singular submanifolds are not in general restrictions of holomorphic functions, unlike in the CR nonsingular case. We give a simple condition that
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
On a family of analytic discs attached to a real submanifold M\subset\mathbb{C}^{N+1}
We construct a family of analytic discs attached to a real submanifold M \subset $\mathbb{C}^{N+1}$ of codimension $2$ defined near a CR singularity.


On Levi-flat hypersurfaces with prescribed boundary
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

Some properties of polynomially convex hulls of compact sets in Cn are deduced by simple topological arguments applied to known topological facts about polynomially convex sets. Introduction. It is
