A Vanishing Result for the Universal Bundle on a Toric Quiver Variety

Altmann, Klaus; Hille, Lutz

Let $Q$ be a finite quiver without oriented cycles. Denote by $\UB \ra \cwtM$ the fine moduli space of stable thin sincere representations of $Q$ with respect to the canonical stability notion. We prove $\mExt^l_{\cwtM}(\UB,\UB) ...

The polyhedral Hodge number h2,1

Altmann, Klaus; Straten, Duco van

We prove a vanishing theorem for the Hodge number h2,1 of projective toric varieties provided by a certain class of polytopes. We explain how this Hodge number also gives information about the deformation theory of the ...
