Title : Estimates of Poisson kernels for symmetric Lévy processes  and their applications

Abstract: In this talk, we will discuss estimates of Poisson kernels for symmetric Lévy processes in  open sets. The result covers subordinate Brownian motions with high intensity of small jumps such as conjugate geometric stable processes. As applications, we obtain the boundary Harnack principle and existence of tangential limits for harmonic functions in  open sets.
