Let $$F$$F be a proper rational map from the complex ball $$\mathbb B ^n$$Bn into $$\mathbb B ^N$$BN with $$n>7$$n>7 and $$3n+1 \le N\le 4n-7$$3n+1≤N≤4n-7. Then $$F$$F is equivalent to a map $$(G, 0, \dots , 0)$$(G,0,⋯,0) where $$G$$G is a proper holomorphic map from $$\mathbb B ^n$$Bn into $$\mathbb B ^{3n}$$B3n. 
On local holomorphic maps preserving invariant (p,p)-forms between bounded symmetric domains
Let $D, \Omega_1, ..., \Omega_m$ be irreducible bounded symmetric domains. We study local holomorphic maps from $D$ into $\Omega_1 \times... \Omega_m$ preserving the invariant $(p, p)$-forms induced

We show that the D’Angelo conjecture holds in the third gap interval. More precisely, we prove that the degree of any rational proper holomorphic map from $${\mathbb {B}}^n$$ B n to $${\mathbb
Mappings between balls with geometric and degeneracy rank two
The paper is devoted to the study of rational proper holomorphic maps from the unit ball $$\mathbb{B}^n$$Bn to the unit ball $$\mathbb{B}^N$$BN. We classify these maps with both the geometric rank
Proper holomorphic mappings into $\ell$-concave quadric domains in projective space

Let $ \B^{n+1} \subset \C^{n+1}$ be the unit ball in a complex Euclidean space, and let $ \Sigma^n = \partial \B^{n+1} = S^{2n+1}$. Let $ f: \Sigma^n \hook \Sigma^{N}$ be a local CR immersion.If $
Regularity of CR mappings between algebraic hypersurfaces
We prove that if $M$ and $M'$ are algebraic hypersurfaces in $ C^ N$, i.e. both defined by the vanishing of real polynomials, then any sufficiently smooth CR mapping with Jacobian not identically
A new gap phenomenon for proper holomorphic mappings from B^n into B^N
In this paper (Math. Res. Lett. 13 (2006). No 4, 509-523), the authors established a pseudo-normal form for proper holomoprhic mappings between balls in complex spaces with degenerate rank. This then

A sharp bound for the degree of proper monomial mappings between balls
The authors prove that a proper monomial holomorphic mapping from the two-ball to the N-ball has degree at most 2N-3, and that this result is sharp. The authors first show that certain
