Some examples of extremal triples of commuting contractions

Edward J. Timko

The collection $\frk{C}_3$ of all triples of commuting contractions forms a family in the sense of Agler, and so has an "optimal" model $\pd\frk{C}_3$ generated by its extremal ele…

On polynomial $n$ -tuples of commuting isometries

Edward J. Timko

We extend some of the results of Agler, Knese, and McCarthy [1] to $n$ -tuples of commuting isometries for $n > 2$ . Let $V = (V_{1}, \dots, V_{n})$ be an $n$ -tuple of a commuting iso…
