我们研究了与克罗内克颤振不可分解表示相关的格拉斯曼颤振。我们找到它们的细胞分解并计算它们的贝蒂数。作为应用,我们给出了类型为$A_2^{(1)}$的Kronecker型簇代数(Sherman和Zelevinsky发现)的“正则基”的几何实现。
We study quiver Grassmannians associated with indecomposable representations of the Kronecker quiver. We find a cellular decomposition of them and we compute their Betti numbers. As an application, we give a geometric realization of the "canonical basis" of cluster algebras of Kronecker type (found by Sherman and Zelevinsky) and of type $A_2^{(1)}$.
