| Abstract | Torus fixed points of quiver moduli spaces are given by stable
representations of the universal covering quiver. As far as the Kronecker
quiver is concerned they can be described by stable representations of
certain bipartite quivers coming along with a stable colouring. By use of
the glueing method it is possible to construct a huge class of such
quivers implying a lower bound for the Euler characteristic. For certain
roots it is even possible to construct all torus fixed points. Moreover,
for each root of the generalized Kronecker quiver it is possible to
construct indecomposable tree modules of the Kronecker quiver. |
