Posinormal Composition Operators on $H^{2}$

Paul S. Bourdon, Derek Thompson

A bounded linear operator $A$ on a Hilbert space is posinormal if there exists a positive operator $P$ such that $A A^{*} = A^{*} P A$ . Posinormality of $A$ is equivalent to the inclu…

The norm of a skew polynomial

Susanne Pumpluen, Daniel Thompson

Let $D$ be a finite-dimensional division algebra over its center and $R = D [t; σ, δ]$ a skew polynomial ring. Under certain assumptions on $δ$ and $σ$ , the ring of central quotients $D…
