    • Invariant Algebraic Curves of Generalized Liénard Polynomial Differential Systems 

      Giné, Jaume; Llibre, Jaume (MDPI, 2022)
      In this study, we focus on invariant algebraic curves of generalized Liénard polynomial differential systems x 0 = y, y 0 = −fm(x)y − gn(x), where the degrees of the polynomials f and g are m and n, respectively, and ...
    • Liénard equation and its generalizations 

      Giné, Jaume (World Scientific Publishing, 2017)
      In this paper, we first present a survey of the known results on limit cycles and center conditions for Liénard differential systems. Next we propose a generalization of such systems and we study their center conditions ...
