紧致Hessian流形上的蒙日-安培方程

Monge-Ampère equations on compact Hessian manifolds

Vincent Guedj, Tat Dat Tô

摘要:

考虑紧致Hessian流形上的退化蒙日-安培方程.我们建立了规范化拟凸函数集的紧性,并给出了扭曲Monge-Ampère算子的局部和整体比较原理.然后,我们使用Perron方法来求解蒙日-安培方程,其RHS涉及任意的概率测度,推广了Cheng-Yau、Delanoë、Caffarelli-Viaclovsky和Hultgren-Önnheim的工作。我们开发的内在方法应该是有用的,在轻度奇异的海森品种,在符合Strominger-丘-Zaslow猜想推导出类似的结果。

英文摘要:

We consider degenerate Monge-Ampère equations on compact Hessian manifolds. We establish compactness properties of the set of normalized quasi-convex functions and show local and global comparison principles for twisted Monge-Ampère operators. We then use the Perron method to solve Monge-Ampère equations whose RHS involves an arbitrary probability measure, generalizing works of Cheng-Yau, Delanoë, Caffarelli-Viaclovsky and Hultgren-Önnheim. The intrinsic approach we develop should be useful in deriving similar results on mildly singular Hessian varieties, in line with the Strominger-Yau-Zaslow conjecture.
