关于分数阶Monge-Ampère算子

On a fractional Monge-Ampère operator

Luis Caffarelli, Fernando Charro

摘要:

本文考虑Monge-Ampère算子的一个分数阶模拟。我们的运营商是一个凹包络的分数线性算子的形式$ \inf_{A\in \mathcal{A}}L_Au, $的运营商的集合对应于所有仿射变换的行列式之一的分数拉普拉斯算子。我们建立了一个相对简单的全球解决方案框架,规定了无限大的数据和全球壁垒。在我们的关键估计,我们表明,运营商保持严格的椭圆,这允许应用已知的正则性结果一致椭圆算子,并推断解决方案是经典的。

英文摘要:

In this paper we consider a fractional analogue of the Monge-Ampère operator. Our operator is a concave envelope of fractional linear operators of the form $ \inf_{A\in \mathcal{A}}L_Au, $ where the set of operators corresponds to all affine transformations of determinant one of a given multiple of the fractional Laplacian. We set up a relatively simple framework of global solutions prescribing data at infinity and global barriers. In our key estimate, we show that the operator remains strictly elliptic, which allows to apply known regularity results for uniformly elliptic operators and deduce that solutions are classical.
