Abstract | |
Motivated by gauge theory under special holonomy, we present techniques to produce holomorphic bundles over certain non-compact 3-folds, called building blocks, satisfying a stability condition `at infinity'. Such bundles are known to parametrize solutions of the Yang-Mills equation over the G2-manifolds obtained from asymptotically cylindrical Calabi-Yau 3-folds studied by Kovalev, Haskins et al. and Corti et al. The most important tool is a generalization of Hoppe's stability criterion to holomorphic bundles over smooth projective varieties X with PicX similar or equal to Z(l), a result which may be of independent interest. Finally, we apply monads to produce a prototypical model of the curvature blow-up phenomenon along a sequence of asymptotically stable bundles degenerating into a torsion-free sheaf. (AU) | |
