Metric flips with Calabi ansatz
arXiv:1011.1608
Abstract
We study the limiting behavior of the Kahler-Ricci flow on , assuming the initial metric satisfies the Calabi symmetry. We show that the flow either shrinks to a point, collapses to or contracts a subvariety of codimension m+1 in Gromov-Hausdorff sense. We also show that the Kahler-Ricci flow resolves certain type of conical singularities in Gromov-Hausdorff sense.
