Let us consider a projective manifold Mn and a smooth volume form Ω on M. We define the gradient flow associated to the problem of Ω-balanced metrics in the quantum formalism, the Ω-balancing flow. At the limit of the quantization, we prove that (see Theorem 1) the Ω-balancing flow converges towards a natural flow in Kähler geometry, the Ω-Kähler flow. We also prove the long time existence of the Ω-Kähler flow and its convergence towards Yau's solution to the Calabi conjecture of prescribing the volume form in a given Kähler class (see Theorem 2). We derive some natural geometric consequences of our study.
