Gauge GW invariants are K-theoretic invariants associated to the moduli space of Gieseker bundles. The moduli spaces are complete but not compact, making it nontrivial to prove well-definedness of the invariants, let alone compute them. We will show that n-pointed gauge GW invariants can be reconstructed from 3-pointed invariants, providing a concrete way to compute these invariants.
