Path energy minimization (PEM), a novel method for the generation of a reaction path linking two known conformers of a molecule, is presented. The technique is based on optimizing a function which closely approximates the peak potential energy of a quasi-continuous path between the fmed end points.
We introduce a method to obtain explicitly periodic solutions of some types of functional differential equations whose periods depend rationally on integral delays. Several applications of this method are given.
