In particular, the asymptotic analysis of the above integral is amenable for the saddle-point method to obtain uniform asymptotic expansions for the coefficients in (4) for ([n.sub.0], n) [member of ] [parallel]([n.sub.0], n) JI .
In order to apply the saddle-point method let 1 be the order of vanishing of F about (0; ([t.sub.0], t); x([t.sub.0], t)) with respect to the variable [theta].
