The Ritt property of subordinated operators in the group case
Florence Lancien, Christian Le Merdy
Let be a locally compact abelian group, let be a regular probability measure on , let be a Banach space, let be a bounded strongly continuous rep…

On functional calculus properties of Ritt operators
Florence Lancien, Christian Le Merdy
We compare various functional calculus properties of Ritt operators. We show the existence of a Ritt operator T : X --> X on some Banach space X with the following property: T has…

On contractive projections in Hardy spaces
Florence Lancien, Beata Randrianantoanina, Eric Ricard
We prove a conjecture of Wojtaszczyk that for , , $H_p(\mathbbT)$ does not admit any norm one projections with dimension of the range finite and bigger tha…
