Abstract in Portuguese
Neste trabalho estudamos a dinâmica de partículas e cordas num campo gravitacional com métrica degenerada. Utilizamos o formalismo Hamiltoniano para determinar os vínculos da teoria e a dinâmica efetiva do sistema. Classificamos a estrutura dos vínculos de acordo com a forma de métrica e dimensão do espaço (-tempo). Obtemos também a representação das simetrias em termos de isometrias geradas por auto-vetores nulos da métrica.

Abstract in English
In this work we stud the dynamics of particles and strings in a gravitational Field with degenerate metric. We use the Hamiltonian formalism to find out the constraints and the effective dynamics of the system. We classify the constraint structure according to the formo the me-tric and the space(time) dimension. We also obtain the representation of the symmetries in terms of the isometries generated by the null eigenvectors of the metric.
