Let \(E_1,\;E_2\) be symmetric quasi Banach function spaces on \((0,\alpha )\;(0<\alpha \le \infty )\). We study some properties of several constructions (the products \(E_1({\mathcal {M}})\odot E_2({\mathcal {M}})\), the Calderón spaces \(E_1({\mathcal {M}})^\theta E_2({\mathcal {M}})^{1-\theta }\), the complex interpolation spaces \((E_1({\mathcal {M}}),E_2({\mathcal {M}}))_\theta \), the real interpolation method \((E_1({\mathcal {M}}),E_2({\mathcal {M}}))_{\theta ,p}\)) in the context of noncommutative symmetric quasi Banach spaces. Under some natural assumptions, we prove

$$\begin{aligned} (E_1({\mathcal {M}}), E_2({\mathcal {M}}))_\theta =E_1({\mathcal {M}})^\theta E_2({\mathcal {M}})^{1-\theta }=E_1^{\left( \frac{1}{\theta }\right) }({\mathcal {M}})\odot E_2^{\left( \frac{1}{1-\theta }\right) }({\mathcal {M}})\;(0<\theta <1). \end{aligned}$$

As application, we extend these result to the noncommutative symmetric quasi Hardy spaces case. We also obtained the real case of Peter Jones’ theorem for noncommutative symmetric quasi Hardy spaces.

关于非交换对称拟Banach空间的乘积及应用

\(E_1,\; E_2 \)\((0,\ alpha)\;(0 <\ alpha \ le \ infty)\)上的对称拟Banach函数空间。我们研究了几种构造(产品\(E_1({\ mathcal {M}})\ odot E_2({\ mathcal {M}})\),Calderón空间\(E_1({\ mathcal {M} })^ \ theta E_2({\ mathcal {M}})^ {1- \ theta} \),复数插值空间\((E_1({\ mathcal {M}}),E_2({\ mathcal {M }}))_ \ theta \),其中的实插值方法\((E_1({\ mathcal {M}}),E_2({\ mathcal {M}}))_ {\ theta,p} \))非交换对称拟Banach空间的上下文。在一些自然假设下,我们证明

$$ \ begin {aligned}(E_1({\ mathcal {M}}),E_2({\ mathcal {M}}))_ \ theta = E_1({\ mathcal {M}})^ \ theta E_2({ \ mathcal {M}})^ {1- \ theta} = E_1 ^ {\ left(\ frac {1} {\ theta} \ right)}({\ mathcal {M}})\ odot E_2 ^ {\ left (\ frac {1} {1- \ theta} \ right)}({\ mathcal {M}})\;(0 <\ theta <1)。\ end {aligned} $$

作为应用,我们将这些结果扩展到非交换对称拟Hardy空间情况。我们还获得了非交换对称拟Hardy空间的Peter Jones定理的实例。
