On a family of pseudohyperbolic disks
Raymond Mortini, Rudolf Rupp
Hyperbolic geometry plays an important role within function theory of the disk. For example, via the Schwarz-Pick Lemma, the isometries of the unit disk with respect to…
Reducibility of invertible tuples to the principal component in commutative Banach algebras
Raymond Mortini, Rudolf Rupp
Let be a complex, commutative unital Banach algebra. We introduce two notions of exponential reducibility of Banach algebra tuples and present an analogue to the Corach-Suárez…
The cone and cylinder algebra
Raymond Mortini, Rudolf Rupp
In this exposition-type note we present detailed proofs of certain assertions concerning several algebraic properties of the cone and cylinder algebras. These include a determinati…
On the Bezout equation in the ring of periodic distributions
Rudolf Rupp, Amol Sasane
A corona type theorem is given for the ring R of periodic distributions in R^d in terms of the sequence of Fourier coefficients of these distributions, which have at most polynomia…
