A class of polynomial planar vector fields with polynomial first integral

Ferragut, Antoni; Galindo Pastor, Carlos; Monserrat Delpalillo, Francisco José (Elsevier, 2015-10-01)

We give an algorithm for deciding whether a planar polynomial differential system has a first integral which factorizes as a product of defining polynomials of curves with only one place at infinity. In the affirmative ...
On the computation of Darboux first integrals of a class of planar polynomial vector fields

Ferragut, Antoni; GALINDO PASTOR, CARLOS; Monserrat Delpalillo, Francisco José (Elsevier, 2019-10-15)

[EN] We study the class of planar polynomial vector fields admitting Darboux first integrals of the type Pi(r)(i=1) f(i)(alpha i), where the alpha(i)'s are positive real numbers and the f(i)'s are polynomials defining ...
