$M I D$ and safe quotients for GRWS

Chafiq Benhida, Raúl E. Curto, George R. Exner

Geometrically regular weighted shifts (in short, GRWS) are those with weights $α (N, D)$ given by $α_{n} (N, D) = \frac{p ^{n} + N}{p ^{n} + D}$ , where $p > 1$ and $(N, D)$ is fixed in…

Geometrically regular weighted shifts

Chafiq Benhida, Raul E. Curto, George R. Exner

We study a general class of weighted shifts whose weights $α$ are given by $α_{n} = \frac{p ^{n} + N}{p ^{n} + D}$ , where $p > 1$ and $N$ and $D$ are parameters so that $(N,D) \in (…
