Metric projections, zeros of optimal polynomial approximants, and some extremal problems in Hardy spaces

Catherine Bénéteau, Raymond Cheng, Christopher Felder +3

The well-known proof of Beurling's Theorem in the Hardy space $H^{2}$ , which describes all shift-invariant subspaces, rests on calculating the orthogonal projection of the unit const…

More properties of optimal polynomial approximants in Hardy spaces

Raymond Cheng, Christopher Felder

This work studies optimal polynomial approximants (OPAs) in the classical Hardy spaces on the unit disk, $H^{p}$ ( $1 < p < \infty$ ). For fixed $f \in H^{p}$ and $n \in N$ , the OP…

Optimal Polynomial Approximants in $H^{p}$

Raymond Centner, Raymond Cheng, Christopher Felder

This work studies optimal polynomial approximants (OPAs) in the classical Hardy spaces on the unit disk, $H^{p}$ ( $1 < p < \infty$ ). In particular, we uncover some estimates concerni…
