Spinors, Twistors and Classical Geometry
Nigel J. Hitchin Mathematical Institute, Woodstock Road, Oxford, OX2 6GG, UK
Abstract:
The paper studies explicitly the Hitchin system restricted to the Higgs fields on a fixed very stable rank 2 bundle in genus 2 and 3. The associated families of quadrics relate to both the geometry of Penrose's twistor spaces and several classical results.
Keywords:
spinor, twistor, quadric, stable bundle.
