►Furthermore, as

$t\to 0+$,

$q(t)$ has the expansion (

►For large

$t$, the asymptotic expansion of

$q(t)$ may be obtained from (

2.4.3) by

*Haar’s method.* This depends on the availability of a comparison function

§34.9 Graphical Method

►The graphical

method establishes a one-to-one correspondence between an analytic expression and a diagram by assigning a graphical symbol to each function and operation of the analytic expression.
…For an account of this

method see

Brink and Satchler (1993, Chapter VII).
For specific examples of the graphical

method of representing sums involving the

$\mathit{3}j,\mathit{6}j$, and

$\mathit{9}j$ symbols, see

Varshalovich et al. (1988, Chapters 11, 12) and

Lehman and O’Connell (1973, §3.3).

►Method (2) is very powerful when applicable (

Andrews (1976, Chapter 5)); however, it is applicable only rarely.

Lehner (1941) uses

Method (2) in connection with the Rogers–Ramanujan identities.

►Method (1) can sometimes be improved by application of convergence acceleration procedures; see §

3.9.

Shanks (1955) applies such

methods in several

$q$-series problems; see

Andrews et al. (1986).

§34.13 Methods of Computation

►Methods of computation for

$\mathit{3}j$ and

$\mathit{6}j$ symbols include recursion relations, see

Schulten and Gordon (1975a),

Luscombe and Luban (1998), and

Edmonds (1974, pp. 42–45, 48–51, 97–99); summation of single-sum expressions for these symbols, see

Varshalovich et al. (1988, §§8.2.6, 9.2.1) and

Fang and Shriner (1992); evaluation of the generalized hypergeometric functions of unit argument that represent these symbols, see

Srinivasa Rao and Venkatesh (1978) and

Srinivasa Rao (1981).

►For

$\mathit{9}j$ symbols,

methods include evaluation of the single-sum series (

34.6.2), see

Fang and Shriner (1992); evaluation of triple-sum series, see

Varshalovich et al. (1988, §10.2.1) and

Srinivasa Rao et al. (1989).

methods of computation is given in
