Asymptotic properties of solutions have been considered for some nonlinear second order dierential equations. The paper deals with investigation of bounded solutions, oscillatory solutions and another asymptotic properties. We also give sucient conditions, in order that the dierential equations of second order has innitely many solutions satisfying Cauchys problem. For general
information is referred a short reference.
