我们研究域 K 上 N×N 矩阵的仿射空间,并考虑在同时行和列操作下稳定的簇。我们证明,直到对称性为止,这些品种中的任何一个都是由有限多个方程定义的。
We look at affine spaces of N× N matrices over a field K, and consider varieties that are stable under simultaneous row and column operations. We prove that up to symmetry, any of these varieties is defined by finitely many equations.
