Harnack inequality for stable processes on d-sets
Krzysztof Bogdan, Andrzej Stós, Paweł Sztonyk · Studia Mathematica · 2003
We investigate properties of functions which are harmonic with respect to $\alpha $-stable processes on $d$-sets such as the Sierpiński gasket or carpet. We prove the Harnack inequality for such functions. For every process we estimate its transition dens
