摘要翻译:
我们证明了齐次XXX海森堡模型的交换哈密顿代数在二维$GL_2$-模张量积的奇异向量子空间上具有单谱。作为副产品,我们证明了在V$中精确地存在$\binom{n}{l}-\binom{n}{l-1}$二维向量子空间$v\子集\c$,使得$\deg f=l,\deg g=n-l+1$和$f(u)g(u-1)-f(u-1)g(u)=(u+1)^n$。

英文摘要:
We show that the algebra of commuting Hamiltonians of the homogeneous XXX Heisenberg model has simple spectrum on the subspace of singular vectors of the tensor product of two-dimensional $gl_2$-modules. As a byproduct we show that there exist exactly $\binom {n}{l}-\binom{n}{l-1}$ two-dimensional vector subspaces $V \subset \C$ with a basis $f,g\in V$ such that $\deg f = l, \deg g = n-l+1$ and $f(u)g(u-1) - f(u-1)g(u) = (u+1)^n$.
