The book deals essentially with systems of polynomial autonomous ordinary differential
equations in two real variables. The emphasis is mainly qualitative, although attention
is also given to more algebraic aspects as a thorough study of the center/focus problem
and recent results on integrability. In the last two chapters the performant software
tool P4 is introduced: based on both algebraic manipulation and numerical calculation,
this was conceived for the purpose of drawing "Polynomial Planar Phase Portraits"
on part of the plane, or on a Poincaré compactification, or even on a Poincaré-Lyapunov
compactification of the plane. From the start, differential systems are represented
by vector fields enabling, in full strength, a dynamical systems approach. All essential
notions, including invariant manifolds, normal forms, desingularization of singularities,
index theory and limit cycles, are introduced and the main results are proved for
smooth systems with the necessary specifications for analytic and polynomial systems.
The book is very appropriate for a first course in dynamical systems, presenting the
basic notions in the study of individual two dimensional systems. Not only does it
provide simple and appropriate proofs, but it also contains a lot of exercises and
presents a survey of interesting results with the necessary references to the literature
