Embedding subsets of tori Properly into 2

Erlend Fornæss Wold (2007)

Annales de l’institut Fourier

Let 𝕋 be a complex one-dimensional torus. We prove that all subsets of 𝕋 with finitely many boundary components (none of them being points) embed properly into 2 . We also show that the algebras of analytic functions on certain countably connected subsets of closed Riemann surfaces are doubly generated.

Extension d'homéomorphismes CR entre variétés polynômialement rigides.

Patrick Lahondès (2002)

Publicacions Matemàtiques

Let f : M → M' be a CR homeomorphism between two minimal, rigid polynomial varieties of Cn without holomorphic curves. We show that f extends biholomorphically in a neighborhood of M if f extends holomorphically in a neighborghood of a point p0 ∈ M or if f is of class C1. In the other hand, in case M and M' are two algebraic hypersurfaces, we obtain the extension without supplementary conditions.

Extension of germs of holomorphic isometries up to normalizing constants with respect to the Bergman metric

Ngaiming Mok (2012)

Journal of the European Mathematical Society

We study the extension problem for germs of holomorphic isometries f : ( D ; x 0 ) ( Ω ; f ( x 0 ) ) up to normalizing constants between bounded domains in Euclidean spaces equipped with Bergman metrics d s D 2 on D and d s Ω 2 on Ω . Our main focus is on boundary extension for pairs of bounded domains ( D , Ω ) such that the Bergman kernel K D ( z , w ) extends meromorphically in ( z , w ¯ ) to a neighborhood of D ¯ × D , and such that the analogous statement holds true for the Bergman kernel K Ω ( ς , ξ ) on Ω . Assuming that ( D ; d s D 2 ) and ( Ω ; d s Ω 2 ) are complete Kähler manifolds, we prove that the germ...

Formules de Jacobi et méthodes analytiques

Hai Zhang (2005)

Colloquium Mathematicae

On se propose de retrouver, via des méthodes d'inspiration analytiques basées sur l'utilisation de formules de représentation intégrale attachées à des applications holomorphes propres d'un ouvert de ℂⁿ dans ℂⁿ, les formules de Jacobi généralisées obtenues par C. A. Berenstein, A. Vidras et A. Yger; le fait de disposer de telles preuves (basées sur un raisonnement limité au cadre strictement affine et ne nécessitant pas le recours à une compactification) autorise l'extension de ces résultats au...

Hölder continuity of proper holomorphic mappings

François Berteloot (1991)

Studia Mathematica

We prove the Hölder continuity for proper holomorphic mappings onto certain piecewise smooth pseudoconvex domains with "good" plurisubharmonic peak functions at each point of their boundaries. We directly obtain a quite precise estimate for the exponent from an attraction property for analytic disks. Moreover, this way does not require any consideration of infinitesimal metric.
