报告摘要: In 1972, Gabriel showed that a connected quiver is of finite representation type iff it is a Dynkin quiver (thus of type A_n, D_n, E_6, E_7, E_8). In this way, the representation categories of the Dynkin quivers may be considered as categorifications of the corresponding finite root systems. Soon after, the Euclidean quivers were shown to be of tame representation type and to be the minimal representation infinite quivers.All this came as a big surprise and was the start of a very fruitful development relating the representation theory of finite-dimensional algebras in a non-trivial way to Lie theory. The lecture will outline a direct approach to the representation theory of Dynkin and Euclidean quivers, with special emphasis on the exceptional cases E_6, E_7, E_8.
