Continuity of the relative extremal function on analytic varieties in ℂⁿ

Frank Wikström (2005)

Annales Polonici Mathematici

Let V be an analytic variety in a domain Ω ⊂ ℂⁿ and let K ⊂ ⊂ V be a closed subset. By studying Jensen measures for certain classes of plurisubharmonic functions on V, we prove that the relative extremal function ω K is continuous on V if Ω is hyperconvex and K is regular.

Contribution du cup-produit de la fibre de Milnor aux pôles de | f | 2 λ

Daniel Barlet (1984)

Annales de l'institut Fourier

Nous montrons comment un cup-produit non trivial entre deux blocs de Jordan pour une même valeur propre de la monodromie agissant sur la cohomologie de la fibre de Milnor d’un germe de fonction holomorphe f provoque des pôles d’ordres élevés pour le prolongement méromorphe de | f | 2 z . Pour la valeur propre 1 ceci donne en particulier le phénomène de “contribution sur-effective”.

Convergence of holomorphic chains

Sławomir Rams (1997)

Annales Polonici Mathematici

We endow the module of analytic p-chains with the structure of a second-countable metrizable topological space.

Cyclic coverings of Fano threefolds

Sławomir Cynk (2003)

Annales Polonici Mathematici

We describe a series of Calabi-Yau manifolds which are cyclic coverings of a Fano 3-fold branched along a smooth divisor. For all the examples we compute the Euler characteristic and the Hodge numbers. All examples have small Picard number ϱ = h 1 , 1 .

Decomposition into special cubes and its applications to quasi-subanalytic geometry

Krzysztof Jan Nowak (2009)

Annales Polonici Mathematici

The main purpose of this paper is to present a natural method of decomposition into special cubes and to demonstrate how it makes it possible to efficiently achieve many well-known fundamental results from quasianalytic geometry as, for instance, Gabrielov's complement theorem, o-minimality or quasianalytic cell decomposition.

Definable stratification satisfying the Whitney property with exponent 1

Beata Kocel-Cynk (2007)

Annales Polonici Mathematici

We prove that for a finite collection of sets A , . . . , A s k + n definable in an o-minimal structure there exists a compatible definable stratification such that for any stratum the fibers of its projection onto k satisfy the Whitney property with exponent 1.
