With this invariant it is possible to predict bifurcation results, as well as results of regularization of the discontinuous field. In Conley’s Theory, one doesn’t investigate only a single invariant set in a system; on the contrary, it is a decomposition of an invariant set into several “smaller” invariant subsets along with the orbits that connect these subsets. The methodology adopted for the research was based on the deductive analy- sis, a method that allowed the determination of the Conley index using tools of differential inclusions, index-pair and Morse theory to arrive at the determination of the homological in- dex. / O presente trabalho trata de temas da matemática denominados a teoria de Conley, inclusões diferenciais e teoria de Morse inserido nesta variante encontra-se o invariante topológico pa- ra a região de descontinuidade, o índice de Conley de campos de vetores descontínuos, onde as descontinuidades estão concentradas numa superfície. Com este invariante é possível pre- ver resultados de bifurcação, bem como resultados de regularização de campos descontínuos. Na Teoria de Conley, não se investiga somente um único conjunto invariante em um siste- ma, pelo contrário, trata-se de uma decomposição de um conjunto invariante em vários sub- conjuntos invariantes "menores" juntamente com as órbitas que conectam estes subconjuntos. A metodologia adotada para a pesquisa se fundamentou na análise dedutiva, método que per- mitiu determinar o índice de Conley utilizando ferramentas de inclusões diferenciais, par-ín- dice e a teoria de Morse para se chegar a determinação do índice homológico.
