Amenable and inner amenable actions and approximation properties for crossed products by locally compact groups
Andrew McKee, Reyhaneh Pourshahami
Amenable actions of locally compact groups on von Neumann algebras are investigated by exploiting the natural module structure of the crossed product over the Fourier algebra of th…

We obtain descriptions of central operator-valued Schur and Herz-Schur multipliers, akin to a classical characterisation due to Grothendieck, that reveals a close link between cent…
