Weighted holomorphic polynomial approximation

S. Charpentier, N. Levenberg, F. Wielonsky

For $G$ an open set in $C$ and $W$ a non-vanishing holomorphic function in $G$ , in the late 1990's, Pritsker and Varga characterized pairs $(G, W)$ having the property that…

Boundary value problems and Heisenberg uniqueness pairs

S. Rigat, F. Wielonsky

We describe a general method for constructing Heisenberg uniqueness pairs $(Γ, Λ)$ in the euclidean space $R^{n}$ based on the study of boundary value problems for partial…

An extremal problem for the Bergman kernel of orthogonal polynomials

S. Charpentier, N. Levenberg, F. Wielonsky

Let $Γ \subset C$ be a curve of class $C (2, α)$ . For $z_{0}$ in the unbounded component of $C ∖ Γ$ , and for $n = 1, 2, ...$ , let $ν_{n}$ be a probability measure w…

Polynomials associated to non-convex bodies

N. Levenberg, F. Wielonsky

Polynomial spaces associated to a convex body $C$ in $(R^{+})^{d}$ have been the object of recent studies. In this work, we consider polynomial spaces associated to non-convex $C…

Riesz energy problems with external fields and related theory

Peter Dragnev, Ramon Orive, Edward B. Saff +1

In this paper, we investigate Riesz energy problems on unbounded conductors in $R^{d}$ in the presence of general external fields $Q$ , not necessarily satisfying the growth conditio…

C-transfinite diameter

N. Levenberg, F. Wielonsky

We give a general formula for the $C -$ transfinite diameter $δ_{C} (K)$ of a compact set $K \subset C^{2}$ which is a product of univariate compacta where $C\subset (\mathbb{R}^+…
