Martin boundary associated with a system of PDE

In this paper, we study the Martin boundary associated with a harmonic structure given by a coupled partial differential equations system. We give an integral representation for non negative harmonic functions of this structure. In particular, we obtain such results for biharmonic functions (i.e. 2 ϕ = 0 ) and for non negative solutions of the equation 2 ϕ = ϕ .
