• On the limit cycles of quasihomogeneous polynomial systems 

      González-Ramírez, L. Rocío; Osuna, Osvaldo; Santaella-Forero, Rubén
      In this work, the nonexistence of limit cycles for classes of p - q-quasi-homogeneous polynomial planar systems of weighted degree l is established. Furthermore, we rule out the existence of limits cycles for certain ...
