On the computation of Darboux first integrals of a class of planar polynomial vector fields
(Journal of Mathematical Analysis and Applications, 2019-10-15)
We study the class of planar polynomial vector fields admitting Darboux first integrals of the type ∏i=1 rfi αi, where the αi's are positive real numbers and the fi's are polynomials defining curves with only one place at ...
