Cartan对的Schur乘子

Schur multipliers of Cartan pairs

Rupert H. Levene, Nico Spronk, Ivan G. Todorov, Lyudmila Turowska

摘要:

定义了可分vonNeumann代数M的Schur乘子,推广了经典的$B(\ell^2)$的Schur乘子.我们把这些映射作为M上的正规A-双模映射。若M包含一个同构于超有限II_1因子的直和项,则证明了由扩展Haagerup张量积$A \otimes_{eh} A$产生的Schur乘子严格包含在所有Schur乘子的代数中.

英文摘要:

We define the Schur multipliers of a separable von Neumann algebra M with Cartan masa A, generalising the classical Schur multipliers of $B(\ell^2)$. We characterise these as the normal A-bimodule maps on M. If M contains a direct summand isomorphic to the hyperfinite II_1 factor, then we show that the Schur multipliers arising from the extended Haagerup tensor product $A \otimes_{eh} A$ are strictly contained in the algebra of all Schur multipliers.
