Orthogonal polynomials for area-type measures and image recovery

E. B. Saff, H. Stahl, N. Stylianopoulos +1

Let $G$ be a finite union of disjoint and bounded Jordan domains in the complex plane, let $K$ be a compact subset of $G$ and consider the set $G^{⋆}$ obtained from $G$ …

Sets of Minimal Capacity and Extremal Domains

Herbert R Stahl

Let f be a function meromorphic in a neighborhood of infinity. The central problem in the present investigation is to find the largest domain D \subset C to which the function f ca…

Weighted Extremal Domains and Best Rational Approximation

Laurent Baratchart, Herbert Stahl, Maxim Yattselev

Let f be holomorphically continuable over the complex plane except for finitely many branch points contained in the unit disk. We prove that best rational approximants to f of degr…

Proof of the BMV Conjecture

Herbert R. Stahl

We prove the BMV (Bessis, Moussa, Villani, 1975) conjecture, which states that the function t -> Tr exp(A-tB), t \geq 0, is the Laplace transform of a positive measure on [0,\infty…

The support of the logarithmic equilibrium measure on sets of revolution in $R^{3}$

D. P. Hardin, E. B. Saff, H. Stahl

For surfaces of revolution $B$ in $R^{3}$ , we investigate the limit distribution of minimum energy point masses on $B$ that interact according to the logarithmic potential $\log (1/…

Best uniform rational approximation of $x^{α}$ on $[0, 1]$

Herbert Stahl

A strong error estimate for the uniform rational approximation of $x^{α}$ on $[0, 1]$ is given, and its proof is sketched. Let $E_{nn} (x^{α}, [0, 1])$ denote the minimal approximation err…
