We present a set of conditions enabling a polynomial system of ordinary differential equations in the plane to have invariant algebraic curves. These conditions are necessary and sufficient. Our main tools include factorizations over the field of Pui

We consider a family of cubic Liénard oscillators with linear damping. Particular cases of this family of equations are abundant in various applications, including physics and biology. There are several approaches for studying integrability of the c

In this work the algebraic characterization of the Darboux, Liouville, and Puiseux first integrals of the vocal fold model is given. The multiple Puiseux solutions, also defined in Puiseux integrability, are studied for the first time. The first auth
