Robert J. Berman

摘要:

本文给出了R^n中满足第二边值问题的蒙日-安培方程关于给定目标凸体P)的解的一种新的概率构造,它自然地适合于最优输运理论.更确切地说,某些β-变形永久(玻色子)N粒子点过程的介绍和经验措施,在大的N-限制,显示出指数收敛概率的确定性措施,其潜力满足真正的蒙日-安培方程的问题。特别是,这使我们能够代表的解决方案作为一个限制,因为N趋于无穷大的显式积分的N倍产品的R^n,它也导致明确的极限公式的最优输运映射到凸体P.连接到研究凯勒-爱因斯坦度量的复代数簇,特别是复曲面的,简要讨论。

英文摘要:

We give a new probabilistic construction of solutions to real Monge-Ampère equations in R^n satisfying the second boundary value problem with respect to a given target convex body P) which fits naturally into the theory of optimal transport. More precisely, certain beta-deformed permanental (bosonic) N-particle point processes are introduced and their empirical measures are, in the large N-limit, shown to converge exponentially in probability to a deterministic measure whose potential satisfies the real Monge-Ampère equation in question. In particular, this allows us to represent the solution as a limit, as N tends to infinity of explicit integrals over the N-fold products of R^n and it also leads to explicit limit formulas for optimal transport maps to the convex body P. Connections to the study of Kähler-Einstein metrics on complex algebraic varieties, and in particular toric ones, are briefly discussed.
