17 p, 377.6 KB On the limit cycles for a class of fourth-order differential equations / Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Makhlouf, Ammar (University of Annaba(Algeria). Department of Mathematics)
We provide sufficient conditions for the existence of periodic solutions of the fourth-order differential equation . . . . x + (1 + p2)¨x + p2x = εF(x, x,˙ x, ¨. . . x), where p is a rational different from 0, ε is small and F is a nonlinear function.
