SUMMARY:G_2 geometry and twistor theory - Maciej Dunajski (DAMTP)

CONTACT:Professor Maciej Dunajski
DESCRIPTION:The three-dimensional space of plane parabolas y=ax^2+bx+c adm
 its a natural conformal  structure: Two points are null  separated if the 
 corresponding parabolas are tangent. I shall demonstrate how Riemannian co
 nformal structures in seven dimensions with G_2 structure group arise onmo
 duli spaces of rational curves with self-intersection number six\, or on s
 olution spaces of certain 7th order ODEs.
