Green's function for elliptic systems: existence and Delmotte-Deuschel bounds

Joseph G. Conlon, Arianna Giunti, Felix Otto

We prove that for an open domain $D\subset {\mathbb{R}}^d$ with $d\ge 2$ , for every (measurable) uniformly elliptic tensor field $a$ and for almost every point $y\in D$ , ther…
