Linking solutions for p-Laplace equations with nonlinearity at critical growth

Under a suitable condition on n and p, the quasilinear equation at critical growth\r\n-\Delta_p u=\lambda |u|^{p-2}u + |u|^{p^*-2} u \r\nis shown to admit a nontrivial weak solution u in W^{1,p}_0(\Omega) for any \lambda\geq\lambda_1.\r\nNonstandard linking structures, for the associated functional, are recognized.
