Abstract

We consider the system                                                                       (I) where  is called -Laplacian, W is the open unit ball in    and  is its boundary. We establish upper and lower estimates for possible positive solutions of system (I).

Keywords and phrases: positive radial solutions, -Laplacian problems, boundary value problems.
