RESUMO

In this work we analyzed the Lotka-Volterra system of diferential equations with two preys and a predator, with and without harvesting. Initially we studied the local and global stability of the points of equilibrium in the first model. Later, in the second model, we studied the coefficient of stability of the periodic orbits, by using normal form and numerical estimatives. By using Maple 11, we verified the behavior of the solutions and the appearance of the periodic orbits
