►where ${F}_{0}={f}_{0}$ and $s{F}_{s}$ ($s\ge 1$) is the coefficient of ${x}^{-1}$ in the asymptotic expansion of ${(f(x))}^{s}$ (

…
►it being understood that these equalities are not reversible.
…
►Let $\sum {a}_{s}{x}^{-s}$ be a formal power series (convergent or divergent) and for each positive integer $n$,
…
►Most operations on asymptotic expansions can be carried out in exactly the same manner as for convergent power series.
…For reversion see §2.2.
…
►In those cases it is usually necessary to interpret each infinite series separately in the manner described above; that is, it is not always possible to reinterpret the asymptotic approximation as a single asymptotic expansion.

###### §3.7(ii) Taylor-Series Method: Initial-Value Problems

… ►Similarly, if $w(z)$ is decaying at least as fast as all other solutions along $\mathcal{P}$, then we may reverse the labeling of the ${z}_{j}$ along $\mathcal{P}$ and begin with initial values $w(b)$ and ${w}^{\prime}(b)$. ►###### §3.7(iii) Taylor-Series Method: Boundary-Value Problems

… ►It will be observed that the present formulation of the Taylor-series method permits considerable parallelism in the computation, both for initial-value and boundary-value problems. … ►General methods for boundary-value problems for ordinary differential equations are given in Ascher et al. (1995). …##### 4: 27.13 Functions

►In fact, there are four representations, given by $5={2}^{2}+{1}^{2}={2}^{2}+{(-1)}^{2}={(-2)}^{2}+{1}^{2}={(-2)}^{2}+{(-1)}^{2}$, and four more with the order of summands reversed.

►Mordell (1917) notes that ${r}_{k}\left(n\right)$ is the coefficient of ${x}^{n}$ in the power-series expansion of the $k$th power of the series for $\vartheta \left(x\right)$.
