Abstract<br />

In this work we present basic effects of Qualitative Theory of Differential Equations. We<br />

give a <strong>de</strong>tailed analysis of the phase portrait of planar polinomial differential systems using<br />

invariant manifolds and blow-ups.<br />

Moreover, we analise the phase portrait at infinity using the Poincaré Disc.<br />

Finally we exibe an algorithm used by P4 program to draw the phase portrait.<br />

Keywords: Compactification, Blow-up, Invariant Manifolds, Flows, Phase Portrait.
