(Elsevier, 2011)In this work we study the Liénard differential systems that admit a Weierstrass first integral or a Weierstrass inverse integrating factor
(Elsevier, 2010)The integrability problem consists in finding the class of functions a first integral of a given planar polynomial differential system must belong to. We recall the characterization of systems which admit an elementary or ...
(Springer Science+Business Media New York, 2016-11-15)We study the 3-dimensional center problem at the zero-Hopf singularity in some families of polynomial vector fields arising from third-order polynomial differential equations. After proving some general properties we check ...
