本文综述了Coxeter变换及其在结合代数表示论中的应用研究的最新进展。设Q是一个矩阵,C = C(Q)是相关的Coxeter矩阵。我们认为结果的特征值的C:多重性,分布,界限,关系与对称性的Q…我们考虑应用研究的不可分解模块的遗传代数k[Q](k一个字段):位置的模块,增长的Auslander-Reiten翻译.其他应用关注增长的组成部分的代表性,有限维代数,塔代数.
This work presents a survey (with some proofs) of the recent developments in the study of Coxeter transformations and their applications to representation theory of associative algebras. Let Q be a quiver and C = C(Q) the associated Coxeter matrix. We consider results on the eigenvalues of C: multiplicities, distribution, bounds, relation with the symmetries of Q... We consider applications to the study of the indecomposable modules over the hereditary algebra k[Q] (k a field): position of modules, growth of the Auslander-Reiten translates... Other applications concern growth of components of the representation-quiver of finite dimensional algebras, towers of algebras...
