»ã±¨ÌáÒª£ºIn this talk, we will give a brief review of reflection functors defined by Bernstein, Gelfand and Ponomarev and the generalization of these functors over quiver representations over algebras. Via reflection functors together with Mono and Mepi functors, we show a new proof of the equivalence where is a selfinjective algebra, is an acyclic finite quiver with a sink and is obtained from by reversing all the arrows ending at . This talk is based on the joint work with M. Schmidmeier and discussion with Shijie Zhu.
