Partial regularity and t-analytic sets for Banach function algebras

Joel Feinstein, Raymond Mortini

In this note we introduce the notion of $t$ -analytic sets. Using this concept, we construct a class of closed prime ideals in Banach function algebras and discuss some problems rel…

Holomorphic injective extensions of functions in P(K) and algebra generators

Raymond Mortini

We present necessary and sufficient conditions on planar compacta $K$ and continuous functions $f$ on $K$ in order that $f$ generates the algebras $P (K), R (K), A (K)$ or $C (K)$ . We…

Embedding polydisk algebras into the disk algebra and an application to stable ranks

Raymond Mortini

It is shown how to embed the polydisk algebras (finite and infinite ones) into the disk algebra $A (D)$ . As a consequence, one obtains uniform closed subalgebras…

The Bass and topological stable ranks of the Bohl algebra are infinite

Raymond Mortini, Rudolf Rupp, Amol Sasane

The Bohl algebra $B$ is the ring of linear combinations of functions $t^{k} e^{λ t}$ , where $k$ is any nonnegative integer, and $λ$ is any complex number, with pointwise oper…
