加标号箭图:分类和代数熵
Quivers with additive labelings: classification and algebraic entropy
摘要:
我们证明了Zamolodchikov动力学的经常性有零代数熵,只有当有一个弱次可加的标签,并推测相反。通过给每个箭图赋予一对广义的仿射型Cartan矩阵,并加上一个附加标号,我们对这类箭图进行了完全分类,得到了$40$无限族和$13$例外箭图.这就完成了Zamolodchikov周期箭图和可积箭图的分类程序。
英文摘要:
We show that Zamolodchikov dynamics of a recurrent quiver has zero algebraic entropy only if the quiver has a weakly subadditive labeling, and conjecture the converse. By assigning a pair of generalized Cartan matrices of affine type to each quiver with an additive labeling, we completely classify such quivers, obtaining $40$ infinite families and $13$ exceptional quivers. This completes the program of classifying Zamolodchikov periodic and integrable quivers.
