AI中文摘要:
我们通过显式双射,给出了域上等定向循环箭图幂零表示的几何描述。在有限域上,这得到了幂零表示个数的公式,以及一个表示为幂零的概率公式,我们还按秩对其进行了细化。在布尔半环上,我们将幂零半表示与有向无环图对应,推导了其个数的递归公式,并确定了幂零概率的渐近衰减率。
英文摘要:
We give a geometric description of nilpotent representations of equioriented cyclic quivers over a field via an explicit bijection. Over a finite field, this yields formulas for the number of nilpotent representations and for the probability that a representation is nilpotent. We also give a refinement by rank. Over the Boolean semiring, we identify nilpotent semirepresentations with directed acyclic graphs, derive a recursive formula for their number, and determine the asymptotic decay rate of the probability of nilpotence.
