## Abstract

In this paper, we investigate solutions of the hyperbolic Poisson equation Δ _{h}u(x) = ψ(x) , where ψ∈ L^{∞}(B^{n}, R^{n}) and (Formula Presented.)Δhu(x)=(1-|x|2)2Δu(x)+2(n-2)(1-|x|2)∑i=1nxi∂u∂xi(x)is the hyperbolic Laplace operator in the n-dimensional space R^{n} for n≥ 2. We show that if n≥ 3 and u∈ C^{2}(B^{n}, R^{n}) ∩ C(B^{n}¯ , R^{n}) is a solution to the hyperbolic Poisson equation, then it has the representation u= P_{h}[ ϕ] - G_{h}[ ψ] provided that u∣Sn-1=ϕ and ∫Bn(1-|x|2)n-1|ψ(x)|dτ(x)<∞. Here P_{h} and G_{h} denote Poisson and Green integrals with respect to Δ _{h}, respectively. Furthermore, we prove that functions of the form u= P_{h}[ ϕ] - G_{h}[ ψ] are Lipschitz continuous.
