Resumo

The aim of this paper is to establish two results about multiplicity of solutions to problems involving the 1-Laplacian operator, with nonlinearities with critical growth. To be more specific, we study the following problem [-Delta(u)(1) + xi u/vertical bar u vertical bar = lambda vertical bar u vertical bar(q-2)u + vertical bar u vertical bar(1{*})-2u, in Omega, u=0, on partial derivative Omega, where Omega is a smooth bounded domain in R-N, N >= 2 and xi is an element of [0, 1]. Moreover, lambda > 0, q is an element of (1, 1{*}) and 1{*} = N/N-1. The first main result establishes the existence of many rotationally non-equivalent and nonradial solutions by assuming that xi = 1, Omega= [x is an element of RN : r < |x| < r + 1], N > 2, N not equal 3 and r > 0. In the second one, is a smooth bounded domain, xi = 0, and the multiplicity of solutions is proved through an abstract result which involves genus theory for functionals which are sum of a C1 functional with a convex lower semicontinuous functional.
