An Aubin continuity path for shrinking gradient K\"ahler-Ricci solitons

Differential Geometry 2024-06-06 v3

Abstract

Let DD be a toric K\"ahler-Einstein Fano manifold. We show that any toric shrinking gradient K\"ahler-Ricci soliton on certain toric blowups of C×D\mathbb{C}\times D satisfies a complex Monge-Amp\`ere equation. We then set up an Aubin continuity path to solve this equation and show that it has a solution at the initial value of the path parameter. This we do by implementing another continuity method.
