alg-geom/9510003 | Instantons and affine Lie algebras | Various constructions of the affine Lie algebra action on the homology group
of moduli spaces of instantons on 4-manifolds are discussed. The analogy
between the local-global principle and the role of mass is also explained. The
detailed proofs are given in separated papers \cite{Na-algebra,Na-Hilbert}. | 1995-11-02 | 2011-07-19 | [
