§34.13 Methods of Computation
โบMethods of computation for and 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). โบFor 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). …22: 34.1 Special Notation

§34.9 Graphical Method
โบThe 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 specific examples of the graphical method of representing sums involving the , and symbols, see Varshalovich et al. (1988, Chapters 11, 12) and Lehman and O’Connell (1973, §3.3).24: 34.8 Approximations for Large Parameters
§34.8 Approximations for Large Parameters
โบFor large values of the parameters in the , , and symbols, different asymptotic forms are obtained depending on which parameters are large. … โบand the symbol denotes a quantity that tends to zero as the parameters tend to infinity, as in §2.1(i). … โบUniform approximations in terms of Airy functions for the and symbols are given in Schulten and Gordon (1975b). For approximations for the , , and symbols with error bounds see Flude (1998), Chen et al. (1999), and Watson (1999): these references also cite earlier work.25: 34.3 Basic Properties: Symbol

§16.24(iii) , , and Symbols
โบThe symbols, or Clebsch–Gordan coefficients, play an important role in the decomposition of reducible representations of the rotation group into irreducible representations. They can be expressed as functions with unit argument. The coefficients of transformations between different coupling schemes of three angular momenta are related to the Wigner symbols. These are balanced functions with unit argument. …30: Bibliography G
