##### 1: 17.18 Methods of Computation
Method (1) is applicable within the circles of convergence of the defining series, although it is often cumbersome owing to slowness of convergence and/or severe cancellation. … Method (1) can sometimes be improved by application of convergence acceleration procedures; see §3.9. …
##### 2: 3.8 Nonlinear Equations
The rule converges locally and is cubically convergent. … The convergence of iterative methods …
##### 3: 3.9 Acceleration of Convergence
###### §3.9 Acceleration of Convergence
provided that the right-hand side converges. … Examples are provided by the following analytic transformations of slowly-convergent series into rapidly convergent ones: … For applications to asymptotic expansions, see §2.11(vi), Olver (1997b, pp. 540–543), and Weniger (1989, 2003).
##### 4: T. Mark Dunster
He has received a number of National Science Foundation grants, and has published numerous papers in the areas of uniform asymptotic solutions of differential equations, convergent WKB methods, special functions, quantum mechanics, and scattering theory. …

##### 9: 35.10 Methods of Computation
These algorithms are extremely efficient, converge rapidly even for large values of $m$, and have complexity linear in $m$.
##### 10: 14.13 Trigonometric Expansions
These Fourier series converge absolutely when $\Re\mu<0$. If $0\leq\Re\mu<\frac{1}{2}$ then they converge, but, if $\theta\not=\frac{1}{2}\pi$, they do not converge absolutely. … with conditional convergence for each. …
