Title: Complex structures and zero-curvature equations for sigma-models
Dimitri Bykov (Max-Planck-Institut fur Gravitationsphysik,Potsdam, Allemagne)
I will construct zero-curvature representations for the equations of motion of a class of sigma-models with complex homogeneous target spaces, not necessarily symmetric. As an example, for the case when the target space is a flag manifold and the worldsheet a sphere, I will describe all solutions to the equations of motion. Various ramifications of these results will be described.
