Va. Shefer, LINEARIZATION AND REGULARIZATION OF THE E QUATIONS OF KEPLERIAN MOTION IN A 4-DIMENSIONAL PARAMETRIC SPACE, ASTRONOM ZH, 70(5), 1993, pp. 1113-1119
On the basis of the method described earlier by the author, the proced
ure of linearization and regularization of the differential equations
of motion of the two-body problem in a four-dimensional parametric spa
ce is stated. Together with the integrals of motion and time transform
ation, the transformation of coordinates, generalizing Kustaanheimo -
Stiefel transformation, is used. The given method is applied to the ca
se of a perturbed motion as well.
