• Integrability of planar nilpotent differential systems through the existence of an inverse integrating factor 

  Algaba, Antonio; García, Cristóbal; Giné, Jaume (Elsevier, 2019)

  In this work is characterized the analytic integrability problem around a nilpotent singularity for differential systems in the plane under generic conditions. The analytic integrability problem is characterized via the ...

• Analytic integrability of some examples of degenerate planar vector fields 

  Algaba, Antonio; García, Cristóbal; Giné, Jaume (Springer, 2016)

  This paper is devoted to the classification of analytic integrable cases of two families of degenerate planar vector fields with a monodromic singular point at the origin. This study falls in the still open degenerate ...

• A blow-up method to prove formal integrability for some planar differential systems 

  Fercec, Brigita; Giné, Jaume (Shanghai Normal University & Wilmington Scientific Publisher, 2018)

  In this work we provide an effective method to prove the formal integrability of the resonant saddles. The method is based on the use of a blow-up and the resolution of a recurrence differential equation using induction. ...
