RESUMO

In this work, we study the equation - ?u + ?u = up in the ?, where 1 ? p? n+2/n-2, ? is an open domain in Rn, with n?3. We give special attention to the critical problem, that is, p = n+2/n-2, with Neumann boundary condition in Lipschtzian domains. The main result is on the existence of weak solutions in domains that satisfy some fairly general conditions. In particular, we solve the problem in a semiball. In the second part of the work, we study symmetric domains and find positive solutions that preserve the symmetry of the domain. We investigate, also, if the minimizing solutions preserve some of the symmetry of the domain
