A Hopf Algebra Structure in Self-dual Gravity
Hugo Garcia-Compean, Laura E. Morales, Jerzy F. Plebanski
The two-dimensional non-linear sigma model approach to Self-dual Yang-Mills theory and to Self-dual gravity given by Q-Han Park is an example of the deep interplay between two and…
On Self-dual Gravity Structures on Ground Ring Manifolds in Two-Dimensional String Theory
H. Garcia-Compean, J. F. Plebanski, M. Przanowski
We generalize the geometric structures generated by Witten's ground ring. It is shown that these generalized structures involve in a natural way some geometric constructions from S…
A q-deformed Version of the Heavenly Equations
Jerzy F. Plebanski, H. Garcia-Compean
Using a -deformed Moyal algebra associated with the group of area preserving diffeomorphisms of th two-dimensional torus , sdiff, a -deformed version for the H…
