  • Expansion

    §4.13 has been enlarged. The Lambert W -function is multi-valued and we use the notation W k ⁑ ( x ) , k β„€ , for the branches. The original two solutions are identified via Wp ⁑ ( x ) = W 0 ⁑ ( x ) and Wm ⁑ ( x ) = W ± 1 ⁑ ( x βˆ“ 0 ⁒ i ) .

    Other changes are the introduction of the Wright Ο‰ -function and tree T -function in (4.13.1_2) and (4.13.1_3), simplification formulas (4.13.3_1) and (4.13.3_2), explicit representation (4.13.4_1) for d n W d z n , additional Maclaurin series (4.13.5_1) and (4.13.5_2), an explicit expansion about the branch point at z = e 1 in (4.13.9_1), extending the number of terms in asymptotic expansions (4.13.10) and (4.13.11), and including several integrals and integral representations for Lambert W -functions in the end of the section.

  • Equation (27.14.2)
    27.14.2 f ⁑ ( x ) = m = 1 ( 1 x m ) = ( x ; x ) , | x | < 1

    The representation in terms of ( x ; x ) was added to this equation.

  • Paragraph Inversion Formula (in §35.2)

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

  • Equations (15.6.1)–(15.6.9)

    The Olver hypergeometric function 𝐅 ⁑ ( a , b ; c ; z ) , previously omitted from the left-hand sides to make the formulas more concise, has been added. In Equations (15.6.1)–(15.6.5), (15.6.7)–(15.6.9), the constraint | ph ⁑ ( 1 z ) | < Ο€ has been added. In (15.6.6), the constraint | ph ⁑ ( z ) | < Ο€ has been added. In Section 15.6 Integral Representations, the sentence immediately following (15.6.9), “These representations are valid when | ph ⁑ ( 1 z ) | < Ο€ , except (15.6.6) which holds for | ph ⁑ ( z ) | < Ο€ .”, has been removed.

  • Equation (5.11.8)

    It was reported by Nico Temme on 2015-02-28 that the asymptotic formula for Ln ⁑ Ξ“ ⁑ ( z + h ) is valid for h ( β„‚ ) ; originally it was unnecessarily restricted to [ 0 , 1 ] .
