Grassmannian与簇代数

Grassmannians and Cluster Algebras

Joshua S. Scott

摘要:

本文证明了Grassmannian $\Bbb{G}(k,n)$的齐次坐标环是由S. Fomin和A.泽列文斯基对具有{ \it有限簇型}的Grassmannian进行了分类,并结合$\Bbb{R}\Bbb{P}^2$中点的几何构型研究了相关的簇变量.

英文摘要:

This paper demonstrates that the homogeneous coordinate ring of the Grassmannian $\Bbb{G}(k,n)$ is a {\it cluster algebra of geometric type} - as defined by S. Fomin and A. Zelevinsky. Grassmannians having {\it finite cluster type} are classified and the associated cluster variables are studied in connection with the geometry of configurations of points in $\Bbb{R}\Bbb{P}^2$.
