Title: | Polynomial Lienard equations near infinity | Authors: | DUMORTIER, Freddy HERSSENS, Chris |
Issue Date: | 1999 | Publisher: | ACADEMIC PRESS INC | Source: | JOURNAL OF DIFFERENTIAL EQUATIONS, 153(1). p. 1-29 | Abstract: | We study the behaviour near infinity of the (generalized) Lienard equations (x) over dot = y, (y) over dot = -Sigma(k=0)(m) a(k)x(k) - y Sigma(k=0)(n) b(k)x(k) providing a complete classification using Poincare compactification as well as Poincare-Lyapunov compactification. We show that all the necessary information is contained in a(m) and b(n), except for the so called "center-focus" problem occuring in case m greater than or equal to 2n + 1 with m, n odd, and where the behaviour also depends on the value of the other coefficients a(i) and b(j). We also indicate how to take care about obtaining uniform information near infinity.
