本文给出了$q$-高斯代数的极大可容子代数的显式例子,即对于实数$q$,生成子代数在$q$-高斯代数内具有绝对值足够小的极大可容子代数。为了达到这个目的,我们以R\u{a}dulescu的精神构造了一个Riesz基,并发展了$q$-高斯代数的一个结构定理。
In this article, we give explicit examples of maximal amenable subalgebras of the $q$-Gaussian algebras, namely, the generator subalgebra is maximal amenable inside the $q$-Gaussian algebras for real numbers $q$ with its absolute value sufficiently small. To achieve this, we construct a Riesz basis in the spirit of R\u{a}dulescu and develop a structural theorem for the $q$-Gaussian algebras.
