This construction includes the case of Nahm transform for periodic instantons on $\bR^4$, the Fourier-Mukai transform for instantons on K3 surfaces, as well as the Nahm transform for ALE instantons.Presented at "Workshop on algebraic structures and moduli spaces", July 14 - 20, 2003, CRM, Univ. de MontrealDifferential Geometrytext
