On degenerations between preprojective modules over wild quivers
We study minimal degenerations between preprojective modules over wild
quivers. Asymptotic properties of such degenerations are studied, with respect
to codimension and numbers of indecomposable direct summands. We provide
families of minimal disjoint degenerations of arbitrary codimension for almost
all wild quivers and show that no such examples exist in the remaining cases.Comment: Proofs improved, several typos corrected. To appear in Journal of
