DESCRIPTION:A quiver is a bunch of arrows. Their representatio
ns provide an important subclass of representation
s of algebras. Gabriel's Theorem classifies when t
he 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 informatio
n is encoded in the derived category of a quiver w
hich has a very nice description as the mesh quive
r. I'll work this all through with the example of
A3. The talk is based on the results in the follow
ing paper.\n\nHappel\, Dieter. "On the derived cat
egory of a finite-dimensional algebra.." Commentar
