title: Displacement norm in the presence of an inverse-square perturbing acceleration in the reference frame associated with the radius vector
abstract: The problem of motion of a zero-mass point under the influence of attraction to the central body and a small perturbing acceleration P′ = P/r 2 is considered, where r is the distance to the attracting center, components of the vector P are assumed to be constant in a reference system with axes directed along the radius vector, the transversal and the angular momentum vector. Previously, for this problem, we found equations of motion in the mean elements and formulas for the transition from the o
