Hartogs type extension theorems on some domains in Kähler manifolds

Takeo Ohsawa (2012)

Annales Polonici Mathematici

Given a locally pseudoconvex bounded domain Ω, in a complex manifold M, the Hartogs type extension theorem is said to hold on Ω if there exists an arbitrarily large compact subset K of Ω such that every holomorphic function on Ω-K is extendible to a holomorphic function on Ω. It will be reported, based on still unpublished papers of the author, that the Hartogs type extension theorem holds in the following two cases: 1) M is Kähler and ∂Ω is C²-smooth and not Levi flat; 2) M is compact Kähler and...

Holomorphic extensions of formal objects

Javier Ribón (2004)

Annali della Scuola Normale Superiore di Pisa - Classe di Scienze

We are interested on families of formal power series in ( , 0 ) parameterized by n ( f ^ = m = 0 P m ( x 1 , , x n ) x m ). If every P m is a polynomial whose degree is bounded by a linear function ( d e g P m A m + B for some A > 0 and B 0 ) then the family is either convergent or the series f ^ ( c 1 , , c n , x ) { x } for all ( c 1 , , c n ) n except a pluri-polar set. Generalizations of these results are provided for formal objects associated to germs of diffeomorphism (formal power series, formal meromorphic functions, etc.). We are interested on describing the nature of the set of parameters where...
