Multiplier ideal sheaves and the Kähler-Ricci flow

Abstract: Multiplier ideal sheaves are constructed as obstructions to the convergence of the Kähler-Ricci flow on Fano manifolds, following earlier constructions of Kohn, Siu, and Nadel, and using the recent estimates of Kolodziej and Perelman.

“…All of these results exploit some underlying structure of the given background to obtain a priori L ∞ estimates for the metric tensor along the flow. In the setting of Kähler-Ricci flow, reduced to a parabolic Monge-Ampere equation, this corresponds to having a C 1,1 estimate for the potential, at which point one applies either the Evans-Krylov method [5,7] to obtain a C 2,α estimate, or Calabi's C 3 estimate [2,18,13], after which Schauder estimates can be applied to obtain C ∞ estimates. As pluriclosed metrics cannot be described locally by a single function, the pluriclosed flow does not admit a scalar reduction, so the method of Evans-Krylov cannot be applied.…”

“…By a conjecture of Yau [40], a necessary and su‰cient condition for M to admit a Kähler-Einstein metric is that M be 'stable in the sense of geometric invariant theory'. Indeed, the problem of using stabil-ity conditions to prove convergence properties of the Kähler-Ricci flow is an area of considerable current interest and we refer the reader to [21], [19], [22], [23], [25], [31], [24], [36] and [5] for some recent advances (however, this list of references is far from complete). One might expect that the su‰ciency part of the Yau-Tian-Donaldson conjecture can be proved via the flow (1.1).…”

“…Multiplier ideal sheaves can also be constructed from the Kähler-Ricci flow ( [14], [17], [8]) and its discretization ( [16], [18]). As mentioned in Remark 1.4, we shall discuss the multiplier ideal sheaves constructed from the Kähler-Ricci flow on the toric del Pezzo surfaces.…”
