摘要: Let A be a basic finite dimensional algebra over an algebraically closed field with radical squared zero, whose ordinary quiver is Q. The homological properties of A are captured by the bounded derived category Db(mod A) of finite dimensional left A-modules. Combining the Koszul equivalence with the derived push-down functor of a minimal gradable Galois covering ˜Q of Q, we obtain a Galois covering functor from D b (rep−( ˜Q op )) to D b (mod A), where rep−(˜Q op ) denotes the category of finitely co-presented representations of ˜Q op . This allows us to describe the shapes of the Auslander-Reiten components of Db(mod A).报告人简介:刘石平,加拿大魁北克Sherbrooke大学教授。湖南师范大学数学系首届研究生,英国利物浦大学博士。曾任挪威Tronheim大学高级讲师、新加坡国立大学讲师。主要从事代数表示论、导出范畴与Cluster范畴研究。
