The Bergman projection on harmonic functions
The boundary Harnack principle for the fractional Laplacian
We study nonnegative functions which are harmonic on a Lipschitz domain with respect to symmetric stable processes. We prove that if two such functions vanish continuously outside the domain near a part of its boundary, then their ratio is bounded near this part of the boundary.

The Functional Equation
The gradient lemma
We show that if a decreasing sequence of subharmonic functions converges to a function in then the convergence is in .
