Abstract in Portuguese
Nesta dissertação são investigados os sistemas diferenciais com integral primeira do tipo Morse-Bott definidos em superfícies compactas e orientáveis. A cada sistema, nas condições acima descritas, associa-se um grafo de modo que a correspondência entre os grafos e as classes de equivalência topologica orbital dos campos investigados seja bijetiva. Portanto, apresenta-se um invariante completo, chamado aqui de grafo de Bott, para essa classe de sistemas. Essa abordagem surgiu como uma iniciativa de generalizar o estudo realizado para sistemas Hamiltonianos com um grau de liberdade com integral primeira do tipo Morse definidos em superfícies 2-dimensionais compactas, onde os conceitos de átomos e fluxos gradiente foram aplicados por A.V. Bolsinov em [4]

Abstract in English
In this dissertation are studied differential systems with a Morse-Bott first integral defined on compact orientable surfaces. For each system, under the conditions described above, is associated a graph so that the correspondence between graphs and the orbital topological equivalence classes of the systems are bijective. Therefore, we present a complete invariant, called here Bott graph for this class of systems. This approach has emerged as an initiative to generalize the study to systems Hamiltonian with one degree of freedom having a Morse first integral in 2-dimensional compact surfaces, where the concepts of atoms and gradient flows were applied by A.V. Bolsinov in [4]
