Lelong classes on toric manifolds and a theorem of Siciak

Maritza M. Branker, Małgorzata Stawiska (2012)

Annales Polonici Mathematici

We generalize a theorem of Siciak on the polynomial approximation of the Lelong class to the setting of toric manifolds with an ample line bundle. We also characterize Lelong classes by means of a growth condition on toric manifolds with an ample line bundle and construct an example of a nonample line bundle for which Siciak's theorem does not hold.

Lelong numbers on projective varieties

Rodrigo Parra (2011)

Annales de la faculté des sciences de Toulouse Mathématiques

Given a positive closed (1,1)-current T defined on the regular locus of a projective variety X with bounded mass near the singular part of X and Y an irreducible algebraic subset of X , we present uniform estimates for the locus inside Y where the Lelong numbers of T are larger than the generic Lelong number of T along Y .

Lempert theorem for strongly linearly convex domains

Łukasz Kosiński, Tomasz Warszawski (2013)

Annales Polonici Mathematici

In 1984 L. Lempert showed that the Lempert function and the Carathéodory distance coincide on non-planar bounded strongly linearly convex domains with real-analytic boundaries. Following his paper, we present a slightly modified and more detailed version of the proof. Moreover, the Lempert Theorem is proved for non-planar bounded strongly linearly convex domains.

Les conditions de Whitney impliquent μ ( * ) constant

Joël Briançon, Jean-Paul Speder (1976)

Annales de l'institut Fourier

La condition “ μ ( * ) constant” est une condition numérique d’équisingularité introduite par B. Teissier. Celui-ci a démontré dans (Astérisque, 7 & 8 (1973) II. Théorème 3.9) que cette condition implique les conditions de Whitney, nous montrons ici la réciproque.
