AI总结:

本文研究了簇代数和τ-倾斜理论中牛顿多面体与簇单项式、τ-刚性模的关系,揭示了其唯一确定性及关键工具。

摘要:

我们证明,在非初始簇变量的簇单项式由其F-多项式的牛顿多面体唯一确定,对于非对称的簇代数。相应地,我们证明,在τ-倾斜理论中,τ-刚性模和左有限多半砖在这些模的牛顿多面体唯一确定。证明中使用了左Bongartz完成、F-不变量和部分F-不变量等工具。

英文摘要:

We prove that the cluster monomials in non-initial cluster variables are uniquely determined by the Newton polytopes of their $F$-polynomials for skew-symmetrizable cluster algebras. Accordingly, we prove that the $τ$-rigid modules and the left finite multi-semibricks in $τ$-tilting theory are uniquely determined by the Newton polytopes of these modules. The key tools used in the proofs are the left Bongartz completion, $F$-invariant and partial $F$-invariant in the context of cluster algebras and $τ$-tilting theory.
