Pick and Peak Interpolation

Alexander J. Izzo

We show how Pick interpolation and interpolation on peak interpolation sets can be combined in an abstract uniform algebra setting. In particular as a special case, the Rudin-Carle…

Gleason parts and point derivations for uniform algebras with dense invertible group

Alexander J. Izzo

It is shown that there exists a compact set $X$ in $C^{N}$ ( $N \geq 2$ ) such that $X ∖ X$ is nonempty and the uniform algebra $P (X)$ has a dense set of invertibl…

A Hull with No Nontrivial Gleason Parts

Brian J. Cole, Swarup N. Ghosh, Alexander J. Izzo

The existence of a nontrivial polynomially convex hull with every point a one-point Gleason part and with no nonzero bounded point derivations is established. This strengthens the…
