Research output: Contribution to journalArticlepeer-review


We show a Poisson formula for bounded harmonic functions φ on the Sierpmski gasket y. We construct a boundary (∑, v), a measurable action of a semigroup W on ∑ and a map r: W y, such that for every bounded harmonic function φ on y φr(w))∫ Ψ(wς)v(dς) where Ψ: φ → IR is some bounded measurable function.
