仿射李代数与Tame箭图

Affine Lie Algebras and Tame Quivers

Igor Frenkel, Anton Malkin, Maxim Vybornov

摘要:

C.M. Ringel定义了与Dynkin型代数的表示范畴相关的Hall代数,并给出了相应李代数的结构常数的明确描述。利用Hall代数的函子性质给出了Ringel结果的一个简单证明,并将其推广到仿射型代数的情形.

英文摘要:

C.M. Ringel defined Hall algebra associated with the category of representations of a quiver of Dynkin type and gave an explicit description of the structure constants of the corresponding Lie algebra. We utilize functorial properties of the Hall algebra to give a simple proof of Ringel's result, and to generalize it to the case of a quiver of affine type.
