$α$ -admissibility of the right-shift semigroup on $L^{2} (R_{+})$

Andrew Wynn

It is shown that the right shift semigroup on $L^{2} (R_{+})$ does not satisfy the weighted Weiss conjecture for $α \in (0, 1)$ . In other words, $α$ -admissibility of scalar value…

Counterexamples to the discrete and continuous weighted Weiss conjectures

Andrew Wynn

Counterexamples are presented to weighted forms of the Weiss conjecture in discrete and continuous time. In particular, for certain ranges of $α$ , operators are constructed that sa…
