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 , which describes all shift-invariant subspaces, rests on calculating the orthogonal projection of the unit const…
Forward operator monoids
Christopher Felder
This work studies collections of Hilbert space operators which possess a strict monoid structure under composition. These collections can be thought of as discrete unital semigroup…
Some Remarks on Shanks-type Conjectures
Christopher Felder
We discuss the zero sets of two-variable polynomials as they relate to an approximation problem in the Hardy space on the bidisk.
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, (). For fixed and , the OP…
Optimal Polynomial Approximants in
Raymond Centner, Raymond Cheng, Christopher Felder
This work studies optimal polynomial approximants (OPAs) in the classical Hardy spaces on the unit disk, (). In particular, we uncover some estimates concerni…
