我们从有限状态自动机理论和代数组合数学出发,提出了一种支持环面作用的量子代数表示理论的新方法。证明了对于固定数m,m×n量子矩阵中的环面不变本原理想可以自然地看作正则语言。利用这种刻画和对Cauchon图集的半群方法,我们证明了对于m固定的m×n量子矩阵中的环面不变本原理想数P(m,n)满足n在有理数上的线性递归.在3×n情形下,我们给出了环面不变本原理想的一个具体刻画,并利用这个刻画给出了P(3,n)数的一个显式。
We develop a new approach to the representation theory of quantum algebras supporting a torus action via methods from the theory of finite-state automata and algebraic combinatorics. We show that for a fixed number m, the torus-invariant primitive ideals in m×n quantum matrices can be seen as a regular language in a natural way. Using this description and a semigroup approach to the set of Cauchon diagrams, a combinatorial object that parameterizes the primes that are torus-invariant, we show that for m fixed, the number P(m,n) of torus-invariant primitive ideals in m×n quantum matrices satisfies a linear recurrence in n over the rational numbers. In the 3×n case we give a concrete description of the torus-invariant primitive ideals and use this description to give an explicit formula for the number P(3,n).
