复曲面Kähler-Einstein度量与凸紧多面体

Toric Kähler-Einstein metrics and convex compact polytopes

Eveline Legendre

摘要:

我们证明了任何紧致凸单格多面体都是Kähler-Einstein orbifold的矩多面体,直到orbifold覆盖和同素性为止是唯一的。本文推广了Wang-Zhu定理\cite{WZ},给出了在满足单调性组合条件的紧致凸单标号多胞形上的复曲面单调流形上的Kähler-Ricci孤子的存在性.我们得到了任何紧凸单多面体$P\subset \bR^n$都有一组内法线,直到膨胀为止是唯一的,使得存在一个辛势满足Guillemin边界条件(关于这些法线)和$P\times \bR^n$上的Kähler-Einstein方程.我们解释我们的结果在环面流形上的奇异Kähler-Einstein度量的存在。

英文摘要:

We show that any compact convex simple lattice polytope is the moment polytope of a Kähler-Einstein orbifold, unique up to orbifold covering and homothety. We extend the Wang-Zhu Theorem \cite{WZ} giving the existence of a Kähler-Ricci soliton on any toric monotone manifold on any compact convex simple labelled polytope satisfying the combinatoric condition corresponding to monotonicity. We obtain that any compact convex simple polytope $P\subset \bR^n$ admits a set of inward normals, unique up to dilatation, such that there exists a symplectic potential satisfying the Guillemin boundary condition (with respect to these normals) and the Kähler-Einstein equation on $P\times \bR^n$. We interpret our result in terms of existence of singular Kähler-Einstein metrics on toric manifolds.
