Os sistemas Hamiltonianos formam uma das classes mais importantes de equações diferenciais. Além de constituírem o formalismo central da física clássica, sua aplicação se estende a uma grande variedade de outros campos de estudo. Esses sistemas possuem uma característica notória do ponto de vista da matemática, a saber, que a sua ação sobre seus estados iniciais preserva uma estrutura geométrica conhecida como simpleticidade. Este fato tem importantes consequências sobre as características qualitativas do comportamento do sistema, em especial no longo prazo. Neste trabalho, são estudados métodos numéricos para obter soluções aproximadas para sistemas Hamiltonianos (já que, via de regra, soluções exatas não podem ser encontradas) que preserv...
