具有（BCP）_θ的重交换的压缩算子组

N-tuple of Doubly Commuting Contraction Operators Possessing (BCP)_θ

本文利用压缩算子组的函数模型，证明了具有（ＢＣＰ）θ的重交换的压缩算子组生成的对偶代数是Ａｓ０代数，从而具有丰富的公共不变子空间。

Using the functional model of n-tuple of contraction operators, we have proved that the dual algebras generated by n-tuple of doubly commuting contraction operators possessing (BCP)θare As。algebras, thus they have rich common invariant subspces.
