Abstract
We define the Schur multipliers of a separable von Neumann
algebra M with Cartan masa A, generalising the classical Schur
multipliers of B(`

). We characterise these as the normal A-bimodule
maps on M. If M contains a direct summand isomorphic to the hyper-
finite II1 factor, then we show that the Schur multipliers arising from
the extended Haagerup tensor product A ⊗eh A are strictly contained
in the algebra of all Schur multipliers.
