The Application of Recurrence Relations to Special Perturbation Methodsase of two body motion. The Taylor method is then applied in turn to the methods of Cowell and Encke in rectangular coordinates, and to a set of perturbational equations using as an example the restricted three body problem. An indication is given of the conditions under which each method is most efficient.

The Three-Dimensional Elliptic Probleme system used is the rotating-pulsating one in which the two primaries are at rest. After developing the method for calculation of three-dimensional periodic orbits and of their stability characteristics, we proceed to present numerical results which were obtained by using the computer 1906A ICL of the University of Manchester.

Regularization Using a Time-Transformation OnlyIt is possible to regularize the perturbed Kepler problem by performing a transformation of the time only. The regularized equations are derived and interpreted, and they are shown to have properties of value in analytic and in numerical applications.

The Particular Solutions of Levi-CivitaTo every invariant manifold (.) of an Hamiltonian system (.) is associated a particular solution. The trajectory is the set of points of (.) for which . is extremal. The time is determined by quadratures..This is an extension of the well-known steady solution associated with an ignorable coordinate.
