三角形矩阵群中的$(k+1)$ -幂矩阵与有限偏序集的关联代数

$(k+1)$-potent Matrices in triangular matrix Groups and Incidence Algebras of Finite Posets

Ivan Gargate, Michael Gargate

摘要:

令$\mathbb{K}$为使得$char(\mathbb{K})\nmid k$和$char(\mathbb{K})\nmid k+1$。本文给出了上三角形矩阵群上的所有$(k+1)$ -幂矩阵.在$\mathbb{K}$是有限域的情况下,给出了如何计算三角形矩阵群中这些元素的个数,并利用这个公式计算关联代数$\mathcal{I}(X,\mathbb{K})$中$(k+1)$ -幂元的个数,其中$X$是有限偏序集.

英文摘要:

Let $\mathbb{K}$ be a field such that $char(\mathbb{K})\nmid k$ and $char(\mathbb{K})\nmid k+1$. We describe all $(k+1)$-potent matrices over the group of upper triangular matrix. In the case that $\mathbb{K}$ is a finite field we show how to compute the number of these elements in triangular matrix groups and use this formula to compute the number of $(k+1)$-potent elements in the Incidence Algebra $\mathcal{I}(X,\mathbb{K})$ where $X$ is a finite poset.
