We study the existence of continuous positive solutions of the m-polyharmonic nonlinear elliptic system
in the complement of the unit closed ball in (n>2m and ). Here the constants are nonnegative, the functions f,g are nonnegative, continuous and monotone. We prove two existence results for the above system subject to some boundary conditions, where the nonnegative functions p,q satisfy some appropriate conditions related to a Kato class of functions.
