A note on the Blum-Hanson property of some contractions on ${\mathrm{L}}^p$-spaces

Cédric Arhancet

If $\Omega$ is a measure space, we show that absolute contractions which are selfadjoint on ${\mathrm{L}}^2(\Omega )$ induce contractions on ${\mathrm{L}}^p(\Omega )$ which satisfy the Blum-Hanson prop…
