论文摘要
我们研究了使用Quiver Grassmannians进行环状颤动的有限尺寸近似仿射旗品种的变性版本。我们证明，它们接收通过仿射型构型参数构元的细胞分解，并且它们的不可还原成分是具有合理颗粒性的正常Cohen-Macaulay品种。
We study finite dimensional approximations to degenerate versions of affine flag varieties using quiver Grassmannians for cyclic quivers. We prove that they admit cellular decompositions parametrized by affine Dellac configurations, and that their irreducible components are normal Cohen-Macaulay varieties with rational singularities.
