If there are expansions of the form (37) – (38
), we have seen that
can be computed according to
Equation (39
). As a consequence, it is of interest to ask if the limit on the right-hand side of this equation
always exists. Due to [79
, Corollary 6.9, p. 1009], the answer is yes. As a consequence, we are naturally led
to the following definition.
Definition 4 Let be a solution to Equations (16
)–(17
) and let
. Then we define
the asymptotic velocity at
to be
