and small time and space. Then we establish a global uniform boundary Harnack principle in (unbounded) open sets for the … global uniform boundary Harnack principle with explicit decay rate. Our boundary Harnack principle is global in the sense …

satisfying a certain growth condition near zero. The main result is a boundary Harnack principle with explicit boundary decay … rate for non-negative harmonic functions of the process in C1,1 open sets. As a consequence of the boundary Harnack … principle, we establish sharp two-sided estimates on the Green function of the subordinate Brownian motion in any bounded C1 …
