Positive isometric Fourier multipliers on non-commutative -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…

Tensor extension properties of C(K)-representations and applications to unconditionality
Christoph Kriegler, Christian Le Merdy
Let K be any compact set. The C^*-algebra C(K) is nuclear and any bounded homomorphism from C(K) into B(H), the algebra of all bounded operators on some Hilbert space H, is automat…
