Weighted Polynomial Approximation of Analytic Functions

Journal of the London Mathematical Society, 1988
For a Borel measure \(d\mu\) on [-1,1] let \(E_ n(f)_{L_ p(d\mu)}\) denote the best approximation of f by polynomials of degree at most n in the space \(L_ p(d\mu)\). Necessary and sufficient condition is given on \(d\mu\) such that the geometric decrease of \(E_ n(f)_{L_ p}(d\mu)\) and the analyticity of f (d\(\mu\)-a.e.) are equivalent.

RATIONAL APPROXIMATION OF ANALYTIC FUNCTIONS

Russian Academy of Sciences. Sbornik Mathematics, 1994
Let \(E\) be an arbitrary compact set in the extended complex plane \(\overline \mathbb{C}\), \(f\) analytic on \(E\), and for any nonnegative integer \(n\) let \(\rho_ n\) denote the uniformly best error of the rational approximation of \(f\) on \(E\), i.e.
