广义簇代数的相伴簇代数

Companion cluster algebras to a generalized cluster algebra

Tomoki Nakanishi, Dylan Rupel

摘要:

研究了满足正规化条件和幂条件的广义簇代数的$c$ -向量、$g$ -向量和$F$ -多项式,恢复了经典的递归和分离加法公式.我们建立了这样一个广义簇代数与它的(左-和右-)同伴簇代数的$c$-向量、$g$ -向量和$F$ -多项式之间的关系。我们的主要结果表明,集群变量和(左和右)同伴集群代数的系数可以通过$F$ -多项式的特殊化恢复。

英文摘要:

We study the $c$-vectors, $g$-vectors, and $F$-polynomials for generalized cluster algebras satisfying a normalization condition and a power condition recovering classical recursions and separation of additions formulas. We establish a relationship between the $c$-vectors, $g$-vectors, and $F$-polynomials of such a generalized cluster algebra and its (left- and right-) companion cluster algebras. Our main result states that the cluster variables and coefficients of the (left- and right-) companion cluster algebras can be recovered via a specialization of the $F$-polynomials.
