Abstract
Consider the perturbedN-body problem
and assume that at the instantt * allN bodies collide, while theP k remain bounded. It is shown that the motion prior to the instant of collision is essentially the same as in the unperturbedN-body problemP k =0, i.e., the same asymptotic relations are valid in both cases ast→t *.

Notation Bold types indicate vectors; denotes the time derivative d/dt;c j are constants;b,b j ,b j are functions with bounded absolute values on the considered interval, ande j ,e j are functions that approach zero as the argument approaches a certain value (which is given explicitly or from the context); instead off=e 1, e.g., we also writef≈0.
