Abstract

We investigate the metric behavior of the Kähler–Ricci flow on the Hirzebruch surfaces, assuming the initial metric is invariant under a maximal compact subgroup of the automorphism group. We show that, in the sense of Gromov–Hausdorff, the flow either shrinks to a point, collapses to or contracts an exceptional divisor, confirming a conjecture of Feldman–Ilmanen–Knopf. We also show that similar behavior holds on higher-dimensional analogues of the Hirzebruch surfaces.
