Query: Generalized K\"ahler-Ricci flow and the classification of nondegenerate
  generalized K\"ahler surfaces   We study the generalized K\"ahler-Ricci flow on complex surfaces with
nondegenerate Poisson structure, proving long time existence and convergence of
the flow to a weak hyperK\"ahler structure.
