Boundary Behavior of Poisson Integrals on Boundaries of Symmetric Spaces
Department of Mathematics, Faculty of Sciences, University Ibn Tofail, KÚnitra, Morocco
We investigate the boundary behavior of Lp-Poisson integrals for various boundaries of Riemannian Symmetric Spaces of the noncompact type. In particular, we show that if a function F on a Riemannian symmetric space G/K is solution of some invariant differential system associated to a standard parabolic subgroup PE of G then F is the Poisson integral of an Lp-function on the boundary component G/PE if and only if it satisfies a Hardy type condition on a family of K-orbits.
Keywords: Poisson integrals, Hardy-type spaces, Fatou-type theorem.
