Let X = {X(t); t ≥ 0} be the hyperbolic Brownian motion on the real hyperbolic space ℍⁿ = {x ∈ ℝⁿ:xₙ > 0}. We study the Green function and the Poisson kernel of tube domains of the form D × (0,∞)⊂ ℍⁿ, where D is any Lipschitz domain in $ℝ^{n-1}$. We show how to obtain formulas for these functions using analogous objects for the standard Brownian motion in $ℝ^{2n}$. We give formulas and uniform estimates for the set $D_a = {x ∈ ℍⁿ:x₁ ∈ (0,a)}$. The constants in the estimates depend only on the dimension of the space.
