Abstract

We study the moduli space of G2G_2-instantons on (projectively) flat bundles over torsion-free G2G_2-orbifolds. We prove that the moduli space is compact and smooth at the irreducible locus after adding small and generic holonomy perturbations. Consequently, we define an integer-valued invariant that is invariant under C0C^0-deformation of torsion-free G2G_2-structures. We compute this invariant for some orbifolds that arise in Joyce's construction of compact G2G_2-manifolds
