    • Chiellini Hamiltonian Liénard differential systems 

      Giné, Jaume; Llibre, Jaume; Valls, Claudia (Texas State University, 2019)
      We characterize the centers of the Chiellini Hamiltonian Li´enard second-order differential equations x 0 = y, y 0 = −f(x)y − g(x) where g(x) = f(x)(k − α(1 + α) R f(x)dx) with α, k ∈ R. Moreover we study the ...
