16 p, 311.8 KB Many periodic solutions for a second order cubic periodic differential equation / Buica, Adriana (Universitatea Babeş-Bolyai. Departamentul de Matematică (Romania)) ; Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
The aim of this work is to provide results that assure the existence of many isolated T-periodic solutions for T-periodic second-order differential equations of the form x'' = a(t)x+b(t)x2+c(t)x3. We use bifurcation methods, including Malkin functions and results of Fonda, Sabatini and Zanolin. [...]
