量子圈代数、量子簇和量子簇代数

Quantum loop algebras, quiver varieties, and cluster algebras

Bernard Leclerc

摘要:

这些笔记反映了2010年8月在东京举行的第14届代数表示国际会议(ICRA XIV)研讨会上的三个讲座的内容。我们首先介绍量子圈代数及其有限维表示。我们解释特别是中岛的几何描述的不可约的q-字符的分级random品种。然后,我们提出了一个最近的尝试,以了解张量结构的范畴的有限维表示通过集群代数。

英文摘要:

These notes reflect the contents of three lectures given at the workshop of the 14th International Conference on Representations of Algebras (ICRA XIV), held in August 2010 in Tokyo. We first provide an introduction to quantum loop algebras and their finite-dimensional representations. We explain in particular Nakajima's geometric description of the irreducible q-characters in terms of graded quiver varieties. We then present a recent attempt to understand the tensor structure of the category of finite- dimensional representations by means of cluster algebras.
