Abstract

For an abelian surface A, we explicitly construct two new families of stable vector bundles on the generalized Kummer variety Kn(A) for n2. The first is the family of tautological bundles associated to stable bundles on A, and the second is the family of the “wrong-way” fibers of a universal family of stable bundles on the dual abelian surface A^ parametrized by Kn(A). Each family exhibits a smooth connected component in the moduli space of stable bundles on Kn(A), which is holomorphic symplectic but not simply connected, contrary to the case of K3 surfaces.
