چکیده
|
We perturb the differential system ẋ1=-x2(1+x1),ẋ2=x1(1+x1),and ẋk=0 for k=3,.,d inside the class of all polynomial differential systems of degree n in rd,and we prove that at most nd-1 limit cycles can be obtained for the perturbed system using the first-order averaging theory. © 2016 zouhair diab and amar makhlouf.
