Positive isometric Fourier multipliers on non-commutative $L^p$-spaces

Christoph Kriegler, Christian Le Merdy, Safoura Zadeh

For a locally compact group \(G\), let \(\mathcal{L}G\) denote its left group von Neumann algebra and let \(L^p(\mathcal{L}G)\), \(1 \le p \le \infty\), be the corresponding non-co…
