Racines de polynômes de Bernstein

Pierrette Cassou-Noguès (1986)

Annales de l'institut Fourier

On considère un polynôme P , à coefficients réels non négatifs, à deux indéterminées. On montre que la connaissance des pôles des intégrales 0 1 0 1 x 1 β 1 - 1 x 2 β 2 - 1 P ( x 1 , x 2 ) s d x 1 d x 2 donne des renseignements sur les racines du polynômes de Bernstein de P . La détermination des pôles des intégrales peut se faire en utilisant certaines méthodes de Mellin. Des calculs explicites sont donnés.

Relative tangent cone of analytic curves

Danuta Ciesielska (1999)

Annales Polonici Mathematici

The purpose of this paper is to give a characterization of the relative tangent cone of two analytic curves in m with an isolated intersection.

Remarks on the proof of a generalized Hartogs Lemma

Evgeni Chirka, Jean Pierre Rosay (1998)

Annales Polonici Mathematici

This paper is an outgrowth of a paper by the first author on a generalized Hartogs Lemma. We complete the discussion of the nonlinear ∂̅ problem ∂f/∂z̅ = ψ(z,f(z)). We also simplify the proofs by a different choice of Banach spaces of functions.

Removable singularities for weighted Bergman spaces

Anders Björn (2006)

Czechoslovak Mathematical Journal

We develop a theory of removable singularities for the weighted Bergman space 𝒜 μ p ( Ω ) = { f analytic in Ω Ω | f | p d μ < } , where μ is a Radon measure on . The set A is weakly removable for 𝒜 μ p ( Ω A ) if 𝒜 μ p ( Ω A ) Hol ( Ω ) , and strongly removable for 𝒜 μ p ( Ω A ) if 𝒜 μ p ( Ω A ) = 𝒜 μ p ( Ω ) . The general theory developed is in many ways similar to the theory of removable singularities for Hardy H p spaces, B M O and locally Lipschitz spaces of analytic functions, including the existence of counterexamples to many plausible properties, e.g. the union of two compact removable singularities needs not be removable....
