Polynomial Counterexamples to Shanks' Conjecture in Dirichlet-Type Spaces over the Bidisc

Oliver Navío, Daniel Seco

We study optimal polynomial approximants in spaces of Dirichlet-type over the bidisc. Given a nonzero function f, the linear optimal polynomial approximant (opa) to its reciprocal…

Uniqueness sets for functions of Dirichlet-type with restricted Taylor coefficients

Nazar Miheisi, Daniel Seco

Let be a reproducing kernel Hilbert space over the unit disk , where analytic monomials span a dense subset. Given and $Λ\subset…
