摘要翻译：
构造了作用于求值Gl_n[t]-模张量积的多重空间上的Bethe代数与合适的Schubert簇的方案理论交之间的规范同构。此外，我们还证明了作为Bethe代数上模的多重空间与方案理论交的协正则表示是同构的。特别地，这一结果暗示了Bethe代数的谱对于评价参数实值的简单性和相应的Schubert簇的交的横截性。

英文摘要：
  We construct a canonical isomorphism between the Bethe algebra acting on a multiplicity space of a tensor product of evaluation gl_N[t]-modules and the scheme-theoretic intersection of suitable Schubert varieties. Moreover, we prove that the multiplicity space as a module over the Bethe algebra is isomorphic to the coregular representation of the scheme-theoretic intersection.   In particular, this result implies the simplicity of the spectrum of the Bethe algebra for real values of evaluation parameters and the transversality of the intersection of the corresponding Schubert varieties.
