Regularity theory and Green's function for elliptic equations with lower order terms in unbounded domains

Mihalis Mourgoglou

We consider elliptic operators in divergence form with lower order terms of the form $Lu=-$div$\nabla u+bu)-c\nabla u-du$, in an open set $\Omega \subset {\mathbb{R}}^n$, $n\ge 3$, with p…
