Toroidal Grothendieck环与簇代数

Toroidal Grothendieck rings and cluster algebras

Laura Fedele, David Hernandez

摘要:

我们研究了具有几个量子参数的簇代数的变形,称为环形簇代数,它自然地出现在量子仿射代数表示的Grothendieck环的研究中。在这种情况下,我们构建了环形Grothendieck环,我们建立这些是平坦变形的Grothendieck环。证明了对于一类划分有限型簇代数的单缀量子仿射代数的么半群范畴$\mathscr{C}_1$,环面Grothendieck环具有环面簇代数的自然结构.

英文摘要:

We study deformations of cluster algebras with several quantum parameters, called toroidal cluster algebras, which naturally appear in the study of Grothendieck rings of representations of quantum affine algebras. In this context, we construct toroidal Grothendieck rings and we establish these are flat deformations of Grothendieck rings. We prove that for a family of monoidal categories $\mathscr{C}_1$ of simply-laced quantum affine algebras categorifying finite-type cluster algebras, the toroidal Grothendieck ring has a natural structure of a toroidal cluster algebra.
