Estimates of Green Function for Relativistic α-Stable Process

  • MichaŁ Ryznar


We call an Rd-valued stochastic process Xt with characteristic function exp {−t{(m2/α2)α/2m}},ξ∈Rd,m>0, the relativistic α-stable process. In the paper we derive sharp estimates for the Green function of the relativistic α-stable process on C1,1 domains. Using these estimates we provide lower and upper bounds for the Poisson kernel. As another application we derive 3G Theorem and Boundary Harnack Principle for C1,1 domains.
