A constructive approach to Schaeffer's conjecture

Oleg Szehr, Rachid Zarouf

J.J. Schaeffer proved that for $an y$ induced matrix norm and $an y$ invertible $T = T (n)$ the inequality \[\left|\det T\right|\left\Vert T^{-1}\right\Vert \leq\mathcal{S}\left\Vert T\…

$l_{p}$ -norms of Fourier coefficients of powers of a Blaschke factor

Oleg Szehr, Rachid Zarouf

We determine the asymptotic behavior of the $l_{p}$ -norms of the sequence of Taylor coefficients of $b^{n}$ , where $b = \frac{z - λ}{1 - λ ˉ z}$ is an automorphism of the unit disk, $p\…
