| Titre | N=2 supersymmetry on compact four-manifolds, Donaldson invariants and Conformal Field Theory |
| Résumé | The formulation of N=2 supersymmetric gauge theories on compact four manifolds admitting a U(1) isometry will be discussed, deriving a contour integral formula for their partition function. The explicit residue evaluation will be presented for the complex projective plane, showing that it computes equivariant Donaldson invariants. The relation of these results with two- dimensional Conformal Field Theories will be also discussed. |
