Sobre a hipótese de Transversalidade de Arnold em famílias de Operadores Bilaplaciano em variedades Riemannianas

Abstract

Let M be a compact orientable Riemannian manifold with boundary. We first study in this thesis the transversality of a family of metrics via a family of Bilaplacian opera-tors parametrised by the metrics themselves. We next consider a family of Bilaplacian operators with variation of their dominion in flat Riemannian manifolds and establish a condition of transversality in this case. In the case of arbitrary Riemannian manifold, we obtain that the spectrum of 2g. is simple and the set of parameters is residual. We complete this thesis by studying the generic propeties of the eigenvalues of the Laplacian of a family of hyper-surfaces of revolution in the vector space Rn+1
