我们考虑量子格曼空间中的量子Schubert胞格,并通过Schubert胞胞给出素谱的胞格分解。因此,我们证明了在变形参数q不是单位根的一般情况下,所有的素数都是完全素数。量子草地上有一个自然的环面作用,一组素数的细胞分解通过与舒伯特细胞相关的分区上的某些图导致-谱的参数化。有趣的是,在最近关于完全非负Grassman的研究中,对非负细胞也发生了同样的参数化。最后,我们利用胞格分解证明了量子Grassman满足正规分离性和连贯性。
We consider quantum Schubert cells in the quantum grassmannian and give a cell decomposition of the prime spectrum via the Schubert cells. As a consequence, we show that all primes are completely prime in the generic case where the deformation parameterqis not a root of unity. There is a natural torus action ofon the quantum grassmannianand the cell decomposition of the set of-primes leads to a parameterisation of the-spectrum via certain diagrams on partitions associated to the Schubert cells. Interestingly, the same parameterisation occurs for the nonnegative cells in recent studies concerning the totally nonnegative grassmannian. Finally, we use the cell decomposition to establish that the quantum grassmannian satisfies normal separation and catenarity.
