Quiver Grassmannian是GrQ e(V)的变种,它参数化了一个矩阵的表示V的维向量e的子表示[1]。本文的目的是证明标题中的主张,这意味着在不限制Q,V和e的选择的情况下,不可能期望有任何特殊的Grassmannian性质。更确切地说,我们证明:
Quiver Grassmannians are varieties GrQ e (V) parametrizing subrepresentations of dimension vector e of a representation V of a quiver Q [1]. The aim of this note is to prove the claim in the title, which implies that no special properties of quiver Grassmannians can be expected without restricting the choices of Q, V and e. More precisely we prove:
