自由群子因子中阿贝尔子代数的无穷重数

Infinite multiplicity of abelian subalgebras in free group subfactors

Marius Stefan

摘要:

我们得到了Voiculescu的(修改)的自由熵维数的估计生成的${II}_1$ -因子$\mc{M}$与子因子$\mc{N}$包含阿贝尔子代数$\mc{A}$的有限重。特别地,它暗示有限Jones指标的内插自由群子因子不具有有限重数的交换子代数或Cartan子代数。

英文摘要:

We obtain an estimate of Voiculescu's (modified) free entropy dimension for generators of a ${II}_1$-factor $\mc{M}$ with a subfactor $\mc{N}$ containing an abelian subalgebra $\mc{A}$ of finite multiplicity. It implies in particular that the interpolated free group subfactors of finite Jones index do not have abelian subalgebras of finite multiplicity or Cartan subalgebras.
