W^{1,p}(R)中迁移映射的一个尖锐不等式

A sharp inequality for transport maps in W^{1,p}(R) via approximation

Jean Louet, Filippo Santambrogio

摘要:

对于$f$凸的和增的,证明了不等式$ \int f(|U'|) \geq \int f(nT')$,每当$U$是一个单变量的Sobolev函数,$T$是定义在同一区间上的非减映射,其像测度与$U$相同,且函数$n(x)$考虑了$U$在每一点的原像数.这可能适用于一些变分问题在质量运输框架或体积约束下。

英文摘要:

For $f$ convex and increasing, we prove the inequality $ \int f(|U'|) \geq \int f(nT')$, every time that $U$ is a Sobolev function of one variable and $T$ is the non-decreasing map defined on the same interval with the same image measure as $U$, and the function $n(x)$ takes into account the number of pre-images of $U$ at each point. This may be applied to some variational problems in a mass-transport framework or under volume constraints.
