and three formulas similar to (18.17.9)–(18.17.11) by symmetry; compare the second row in Table 18.6.1. … Formulas (18.17.12) and (18.17.13) are fractional generalizations of the differentiation formulas given in (Erdélyi et al., 1953b, §10.9(15)). … In particular, in case of exponential Fourier transforms, we may assume y . … In (18.17.21_1) the branch choice of 2 c 1 for 0 < c < 1 2 is unimportant because on the right-hand side only even powers of 2 c 1 occur after expansion of the Hermite polynomial by (18.5.13). … Many of the Fourier transforms given in §18.17(v) have analytic continuations to Laplace transforms. …
13: 19.12 Asymptotic Approximations
With ψ ( x ) denoting the digamma function (§5.2(i)) in this subsection, the asymptotic behavior of K ( k ) and E ( k ) near the singularity at k = 1 is given by the following convergent series:
19.12.1 K ( k ) = m = 0 ( 1 2 ) m ( 1 2 ) m m ! m ! k 2 m ( ln ( 1 k ) + d ( m ) ) , 0 < | k | < 1 ,
19.12.2 E ( k ) = 1 + 1 2 m = 0 ( 1 2 ) m ( 3 2 ) m ( 2 ) m m ! k 2 m + 2 ( ln ( 1 k ) + d ( m ) 1 ( 2 m + 1 ) ( 2 m + 2 ) ) , | k | < 1 ,
Asymptotic approximations for Π ( ϕ , α 2 , k ) , with different variables, are given in Karp et al. (2007). …

§18.3 Definitions
For finite power series of the Jacobi, ultraspherical, Laguerre, and Hermite polynomials, see §18.5(iii) (in powers of x 1 for Jacobi polynomials, in powers of x for the other cases). Explicit power series for Chebyshev, Legendre, Laguerre, and Hermite polynomials for n = 0 , 1 , , 6 are given in §18.5(iv). … In consequence, additional properties are included in Chapter 14. … For ν and N > 1 2 a finite system of Jacobi polynomials P n ( N 1 + i ν , N 1 i ν ) ( i x ) (called pseudo Jacobi polynomials or Routh–Romanovski polynomials) is orthogonal on ( , ) with w ( x ) = ( 1 + x 2 ) N 1 e 2 ν arctan x . …

  • 18: Mathematical Introduction
    The NIST Handbook has essentially the same objective as the Handbook of Mathematical Functions that was issued in 1964 by the National Bureau of Standards as Number 55 in the NBS Applied Mathematics Series (AMS). … As a consequence, in addition to providing more information about the special functions that were covered in AMS 55, the NIST Handbook includes several special functions that have appeared in the interim in applied mathematics, the physical sciences, and engineering, as well as in other areas. … The first section in each of the special function chapters (Chapters 5–36) lists notation that has been adopted for the functions in that chapter. … Similarly in the case of confluent hypergeometric functions (§13.2(i)). … In the DLMF this information is provided in pop-up windows at the subsection level. …
    19: Errata
  • Paragraph Inversion Formula (in §35.2)

    The wording was changed to make the integration variable more apparent.

  • Subsection 25.2(ii) Other Infinite Series

    It is now mentioned that (25.2.5), defines the Stieltjes constants γ n . Consequently, γ n in (25.2.4), (25.6.12) are now identified as the Stieltjes constants.

  • Equation (33.6.5)
    33.6.5 H ± ( η , ρ ) = e ± i θ ( η , ρ ) ( 2 + 1 ) ! Γ ( ± i η ) ( k = 0 ( a ) k ( 2 + 2 ) k k ! ( 2 i ρ ) a + k ( ln ( 2 i ρ ) + ψ ( a + k ) ψ ( 1 + k ) ψ ( 2 + 2 + k ) ) k = 1 2 + 1 ( 2 + 1 ) ! ( k 1 ) ! ( 2 + 1 k ) ! ( 1 a ) k ( 2 i ρ ) a k )

    Originally the factor in the denominator on the right-hand side was written incorrectly as Γ ( + i η ) . This has been corrected to Γ ( ± i η ) .

  • Equation (34.3.7)
    34.3.7 ( j 1 j 2 j 3 j 1 j 1 m 3 m 3 ) = ( 1 ) j 1 j 2 m 3 ( ( 2 j 1 ) ! ( j 1 + j 2 + j 3 ) ! ( j 1 + j 2 + m 3 ) ! ( j 3 m 3 ) ! ( j 1 + j 2 + j 3 + 1 ) ! ( j 1 j 2 + j 3 ) ! ( j 1 + j 2 j 3 ) ! ( j 1 + j 2 m 3 ) ! ( j 3 + m 3 ) ! ) 1 2

    In the original equation the prefactor of the above 3j symbol read ( 1 ) j 2 + j 3 + m 3 . It is now replaced by its correct value ( 1 ) j 1 j 2 m 3 .

  • Equation (34.4.2)
    34.4.2 { j 1 j 2 j 3 l 1 l 2 l 3 } = Δ ( j 1 j 2 j 3 ) Δ ( j 1 l 2 l 3 ) Δ ( l 1 j 2 l 3 ) Δ ( l 1 l 2 j 3 ) s ( 1 ) s ( s + 1 ) ! ( s j 1 j 2 j 3 ) ! ( s j 1 l 2 l 3 ) ! ( s l 1 j 2 l 3 ) ! ( s l 1 l 2 j 3 ) ! 1 ( j 1 + j 2 + l 1 + l 2 s ) ! ( j 2 + j 3 + l 2 + l 3 s ) ! ( j 3 + j 1 + l 3 + l 1 s ) !

    Originally the factor Δ ( j 1 j 2 j 3 ) Δ ( j 1 l 2 l 3 ) Δ ( l 1 j 2 l 3 ) Δ ( l 1 l 2 j 3 ) was missing in this equation.
