The Affine symmetry of self-dual gravity
Viqar Husain
Self-dual gravity may be reformulated as the two dimensional principal chiral model with the group of area preserving diffeomorphisms as its gauge group. Using this formulation, it…

Self-dual gravity and the chiral model
Viqar Husain
The self-dual Einstein equation (SDE) is shown to be equivalent to the two dimensional chiral model, with gauge group chosen as the group of area preserving diffeomorphisms of a tw…
