Representation theory of Dynkin quivers. Three contributions

Ringel CM. Representation theory of Dynkin quivers. Three contributions. Frontiers of Mathematics in China. 2016;11(4):765-814.The representations of the Dynkin quivers and the corresponding Euclidean quivers are treated in many books. These notes provide three building blocks for dealing with representations of Dynkin (and Euclidean) quivers. They should be helpful as part of a direct approach to study representations of quivers, and they shed some new light on properties of Dynkin and Euclidean quivers
