Ballico E. Gasparim T. K¨oppe Abstract We study moduli of vector bundles on a two-dimensional neighbourhood Zk of an irre-ducible curve ℓ ∼=P1 with ℓ2 = −k and give an explicit construction of their moduli stacks. For the case of instanton bundles, we stratify the stacks and construct moduli spaces.
