Let \({\mathcal {M}}\) be a \(\sigma\)-finite von Neumann algebra, equipped with a normal faithful state \(\varphi\), and let \({\mathcal {A}}\) be maximal subdiagonal subalgebra of \({\mathcal {M}}\) and \(1\le p<\infty\). We prove a Beurling–Blecher–Labuschagne type theorem for \({{\mathcal {A}}}\)-invariant subspaces of Haagerup noncommutative \(L^p({{\mathcal {A}}})\) and give a characterization of outer operators in Haagerup noncommutative \(H^{p}\)-spaces associated with \({{\mathcal {A}}}\).

Haagerup非交换$$ L ^ p $$ L p空间的Beurling–Blecher–Labuschagne型定理

\({\ mathcal {M}} \)\(\ sigma \)有限的冯·诺依曼代数,并配备了正常的忠实状态\(\ varphi \),并令\({\ mathcal {A}} \)\({\ mathcal {M}} \)\(1 \ le p <\ infty \)的最大子对角子代数。我们证明了Haagerup非交换\(L ^ p({^ {mathcal {A}}})\)\({{\ mathcal {A}}} \)-不变子空间的Beurling–Blecher–Labuschagne型定理,并给出与(({{\ mathcal {A}}} \)相关的Haagerup非交换\(H ^ {p} \)-空间中外部算子的刻画。
