چکیده
|
This paper investigates the problem of whether all trajectories of the system x = h(y-f(x)) and y = -g(x) cross the vertical isocline, which is very important for the existence of periodic solutions and oscillation theory. sufficient conditions are given for all trajectories to cross the vertical isocline.
