On the Hartman-Grobman Theorem with Parameters

The Hartman-Grobman Theorem of linearization is extended to families of dynamical systems in a Banach space X, depending continuously on parameters. We prove that the conjugacy also changes continuously. The cases of nonlinear maps and flows are considered, and both in global and local versions, but global in the parameters. To use a special version of the Banach-Caccioppoli Theorem we introduce equivalent norms on X depending on the parameters. The functional setting is suitable for applications to some nonlinear evolution partial differential equations like the nonlinear beam equation.CNPq[301994/85-4]Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Programa Pronex-Projeto Tematico CNPq-FAPESP[2003/10042-0]Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)CAPES[DGU 127/07]MEC-SpainMEC, Spain[MTM2005-07660-C02-01]MEC-SpainMEC, Spain[PHB2006-006
