摘要
In this article, the author studies the boundedness and convergence for the non-Liénard type differential equation {^·x=a(y)-f(x),^·y=b(y)β(x)-g(x)+e(t),where a(y), b(y), f(x), g(x),β(x) are real continuous functions in y ∈ R or x ∈ R, β(x) ≥ 0 for all x and e(t) is a real continuous function on R^+ = {t : t ≥ 0} such that the equation has a unique solution for the initial value problem. The necessary and sufficient conditions are obtained and some of the results in the literatures are improved and extended.
