The determinantal variety Σ p q {\Sigma_{pq}} is defined to be the set of all p × q {p\times q} real matrices with p ≥ q {p\geq q} whose ranks are strictly smaller than q . It is proved that Σ p q {\Sigma_{pq}} is a minimal cone in ℝ p q {\mathbb{R}^{pq}} and all its strata are regular minimal submanifolds.

行列式变量的极小值
行列式变化∑ pq {\ Sigma_ {pq}}被定义为p≥q {p \ geq q}的所有p×q {p \ time q}个实矩阵的集合,其秩严格小于q 。证明∑ pq {\ Sigma_ {pq}}是ℝpq {\ mathbb {R} ^ {pq}}中的一个最小锥,并且其所有层次都是规则的最小子流形。
