由一个局部代数不等式导出的Monge-Ampère算子的估计

Estimates on Monge-Ampère operators derived from a local algebra inequality

Jean-Pierre Demailly

摘要:

这篇短文的目的是将具有孤立或紧支撑奇点的多重次调和函数$ϕ$的指数$e^{-2ϕ}$的可积性与$(dd^cϕ)^n$的蒙格-安培质量的先验界联系起来。该不等式在$\bC^n$中任意开子集$Ω$上局部或全局成立.我们表明,$\int_Ω(ddϕ)^n<n^n$意味着$\int_Ke^{-2ϕ}<+\infty$的每个紧凑的子集$K$在$Ω$,而形式$ϕ(z)=n\log|z-z_0|$,$z_0\inΩ$,出现的功能作为极限情况。这个结果是由A.Corti在$n=2$维上证明的纯局部代数的一个不等式导出的,后验证明它与这个不等式是等价的,后来L.Ein,T.De Fernex和M. Mustaerovich把这个不等式推广到任意维上.

英文摘要:

The goal of this short note is to relate the integrability property of the exponential $e^{-2ϕ}$ of a plurisubharmonic function $ϕ$ with isolated or compactly supported singularities, to a priori bounds for the Monge-Ampère mass of $(dd^cϕ)^n$. The inequality is valid locally or globally on an arbitrary open subset $Ω$ in $\bC^n$. We show that $\int_Ω(ddϕ)^n<n^n$ implies $\int_Ke^{-2ϕ}<+\infty$ for every compact subset $K$ in $Ω$, while functions of the form $ϕ(z)=n\log|z-z_0|$, $z_0\inΩ$, appear as limit cases. The result is derived from an inequality of pure local algebra, which turns out a posteriori to be equivalent to it, proved by A.Corti in dimension $n=2$, and later extended by L.Ein, T.De Fernex and M.Mustaţǎ to arbitrary dimensions.
