DESCRIPTION:A quiver is a bunch of arrows. Their representations provide a
 n important subclass of representations of algebras. Gabriel's Theorem cla
 ssifies when the representation theory of a quiver is finite. In the proof
  of this theorem\, it appears that there is some common information shared
  by quivers with the same underlying graph. This common information is enc
 oded in the derived category of a quiver which has a very nice description
  as the mesh quiver. I'll work this all through with the example of A3. Th
 e talk is based on the results in the following paper.\n\nHappel\, Dieter.
