In this paper we compare diierent continuation methods for the searching of periodic orbits of the Froeschl e map, which is a four dimensional symplectic map. We nd relations between the stability of the periodic orbits and the problem to solve the system given in the continuation method.
Arbovirus constitutes a group of virus that is transmitted by arthropod's bites. Examples of diseases produced by this kind of virus are Dengue, Yellow Fever, and West Nile Virus, among others. These diseases are a major health problem in the world. In this work we formulate a system of differential equations to study the dynamics of an infection produced… (More)
