Spectral versus interpolation norms in tracial nonassociative $L^{p}$ -spaces

Cédric Arhancet, Lei Li

We investigate the metric structure of nonassociative $L^{p}$ -spaces associated with tracial $JW^{*}$ -algebras. While noncommutative $L^{p}$ -spaces arising fro…

On the convex structure of the space of quantum channels which act as Fourier multipliers

Cédric Arhancet, Lei Li

If $G$ is a compact group, continuous normalized positive definite functions are in one-to-one correspondence with unital quantum channels acting as Fourier multipliers on the grou…
