No. of bitstreams: 1 vladimiralfredodionisioarmas.pdf: 1154081 bytes, checksum: 21752bffdb1d22af7d8e8fdff40e121b (MD5) Previous issue date: 2015-07-14 / Neste trabalho é apresentado um estudo sobre a Integral de Melnikov para duas classes de sistemas de equações diferenciais ordinárias. A primeira delas é um sistema Hamiltoniano associado a uma perturbação uniparamétrica. A segunda classe é um sistema geral, associada a uma perturbação bidimensional. O trabalho termina com um estudo sobre a existência e unicidade de solucões do tipo de onda viajante para um modelo matemático de combustão em um meio poroso. / This work presents a study about the Melnikov’s Integral for two classes of ordinary differential equations. In the first one, we study the Melnikov’s Integral for a Hamiltonian system associated with one-parameter perturbation. The second class, we study the Melnikov’s Integral for any system associated with a two-dimensional perturbation. The work finishes with a study on the existence and uniqueness of traveling wave solutions of the mathematical model describing combustion in porous medium.
