Classification of invariant algebraic curves and nonexistence of algebraic limit cycles in quadratic systems from family (I) of the Chinese classification

Demina M.V., Valls C.

We give the complete classi cation of irreducible invariant algebraic curves in family (I) of the
Chinese classi cation. In addition, we provide a complete and correct proof of the non{existence of
algebraic limit cycles for these equations.
