Harmonic mappings, twistors, and σ-models, 9-13 June 1986, CIRM, Luminy, France
Paul Gauduchon · WORLD SCIENTIFIC eBooks · 1988
Harmonic mappings have played in recent years and will likely to play in the future an important role in Differential Geometry and Theoretical Physics, where they are known as s-models. These Proceedings develop both aspects of the theory, with a special attention to the constructive methods, in particular the so-called twistorial approach. It includes expository articles on the twistorial methods, the various appearence of -models in Physics, the powerful analytic theory of regularity of SCHOEN-UHLENBECK.
