摘要
We study some properties of bounded solutions on (0, +infinity) of the following almost periodic Lienard equation: x" + f(x)x' + g(x) = p(t), where p : R --> R is almost periodic function and g : (a, b) --> R is strictly decreasing function. Notably, we describe the set of initial conditions of the bounded solutions on (0, +infinity) and we state that these solutions are asymptotically almost periodic. (C) 2004 Elsevier Ltd.
