广义Kronecker箭图上正则分量的维数向量

Dimension vectors in regular components over wild Kronecker quivers

Bo Chen

摘要:

假设$\mathcal{K}_n$是所谓的野生克罗内克群,即,具有一个源和一个宿以及从源到宿的$n\geq 3$箭头的信标。对Auslander-Reiten算子的任意正则分支$\mathcal{C}$,研究了以下问题:(1)$\mathcal{C}$中不可分解正则表示的维数向量与拟长度之间的关系是什么?(2)对于给定的自然数$d$,$\mathcal{C}$中具有相同长度$d$的不可分解表示的个数是否存在上界?(3)不同正则分支中不可分解表示的维数向量的集合何时重合?

英文摘要:

Let $\mathcal{K}_n$ be the so-called wild Kronecker quiver, i.e., a quiver with one source and one sink and $n\geq 3$ arrows from the source to the sink. The following problems will be studied for an arbitrary regular component $\mathcal{C}$ of the Auslander-Reiten quiver: (1) What is the relationship between dimension vectors and quasi-lengths of the indecomposable regular representations in $\mathcal{C}$? (2) For a given natural number $d$, is there an upper bound of the number of indecomposable representations in $\mathcal{C}$ with the same length $d$? (3) When do the sets of the dimension vectors of indecomposable representations in different regular components coincide?
