关于希尔伯特空间的张量积系的簇系

On cluster systems of tensor product systems of Hilbert spaces

Mithun Mukherjee

摘要:

已知两个乘积系统的空间乘积是内禀的。在这里,我们通过分析乘积系统的张量积的子系统来推广这个结果。与集群系统的关系建立。在一种特殊情况下,我们证明了乘积系统通过严格收缩单位的合并乘积与单位的选择无关。在这种情况下,合并乘积同构于两个空间乘积和指数为1的I型乘积系统的张量积。

英文摘要:

It is known that the spatial product of two product systems is intrinsic. Here we extend this result by analyzing subsystems of the tensor product of product systems. A relation with cluster systems is established. In a special case, we show that the amalgamated product of product systems through strictly contractive units is independent of the choices of the units. The amalgamated product in this case is isomorphic to the tensor product of the spatial product of the two and the type I product system of index one.
