RESUMO

The main aim of this thesis is to introduce a new method for computing the first Dirichlet eigenvalue of the p-Laplacian inspired by the inverse power method of finite dimensional linear algebra. We show the method is valid for any ball in RN, if p >1, and for any bounded domain in the special case p = 2. For p >2 the method is validated numerically for the square and we conjecture that the method is valid for a certain class of domains. We also use the method to compute the generalized sine function introduced by Lindqvist.
