Let Omega be a smooth open bounded subset of R-n with n greater than or equal to 4. Given Sigma subset of Omega any closed, smooth k-dimensionnl submanifold, 1 less than or equal to k < n - 2, with smooth boundary, we prove the existence of infinitly many positive weak solutions of [GRAPHICS] whose singular set is Sigma, provided the exponent p is larger than and close to n-k/n-2-k.
