Query: Mathematical Modeling and Stability of Predator-Prey Systems   This work investigated the stability and asymptotic behavior of some Lotka
Volterra type models. We used the Liapunov method which consists in analyzing
the stability of systems of ordinary differential equations (ODEs) around the
equilibrium when they submitted to perturbations in the initial conditions
