Oscillation theorems for the generalized Lienard system
In this paper we study the qualitative behavior of the solutions of the generalized Lienard system (x) over dot = h(y-F (x)) and (y) over dot = -g(x). We present some new conditions under which the solutions of this system are oscillatory. Some examples are used to illustrate our results. (C) 2011 Elsevier Ltd. All rights reserved.
