Differential equations of differential types with varying complexities have been of great help in several areas of mathematics and sciences. Particularly the solutions of special kinds do take good account of the optimal properties. In the literature the subharmonic solutions with prescribed minimal conditions have been dealt with well. Here the authors have discussed the existence of subharmonic periodic solutions of the equations like: \(x''=-V'(x,t).\) The paper is a very useful attempt at providing references and enlarging the scope of applications of systems of differential equations also.
