Estudos de modelos dispersivos da dinâmica de populações

Abstract

In recent decades the global incidence of dengue has grown dramatically by increased human mobility and urbanization. The study of the mosquito population is of great importance for public health in countries like Brazil, where climatic and environmental conditions are favorable for the propagation of this disease. This work is based on the study of mathematical models dealing with the life cycle of the dengue mosquito using partial differential equations. We investigate the existence of a solution in the form of travelling wave for both models. We use a semi-analytical method combining dynamical systems techniques (e.g. Poincaré section and local analysis based on Hartman-Grobman theorem) and numerical integration using Matlab.
