Query: Phase Diagram of the Two-Dimensional Complex Ginzburg-Landau Equation   After a brief introduction to the complex Ginzburg-Landau equation, some of
its important features in two space dimensions are reviewed. A comprehensive
study of the various phases observed numerically in large systems over the
whole parameter space is then presented. The nature of the transitions between
these phases is investigated and some theoretical problems linked to the phase
diagram are discussed.
