我们讨论了一个与复曲面Kahler-Einstein方程相关的黎曼度量,它以线性不变的方式与(mathbb{R}^{n})中给定的对数凹测度相关联。我们使用这个度量,以约束的解决方案的复曲面Kahler-Einstein方程的二阶导数,并为了获得类似的佩恩和温伯格的谱隙估计。
We discuss a certain Riemannian metric, related to the toric Kahler-Einstein equation, that is associated in a linearly-invariant manner with a given log-concave measure in (mathbb{R}^{n}). We use this metric in order to bound the second derivatives of the solution to the toric Kahler-Einstein equation, and in order to obtain spectral-gap estimates similar to those of Payne and Weinberger.
