Automatic continuity for the unitary group

Todor Tsankov

We show that every homomorphism from the infinite-dimensional unitary or orthogonal group to a separable group is continuous.

Toeplitz condition numbers as an $H^{\infty}$ interpolation problem

Rachid Zarouf

The condition numbers $C N (T) == ∣∣ T ∣∣.∣∣ T^{- 1} ∣∣$ of Toeplitz and analytic $n \times n$ matrices $T$ are studied. It is shown that the supremum of $C N (T)$ over all such matrices wit…

Beurling-Fourier algebras on compact groups: spectral theory

Jean Ludwig, Nico Spronk, Lyudmila Turowska

For a compact group $G$ we define the Beurling-Fourier algebra $A_{ω} (G)$ on $G$ for weights $ω$ defined on the dual $\what G$ and taking positive values. The classical Fourier algeb…
