Legendre Polynomials - Legendre Functions of Fractional Order

Legendre Functions of Fractional Order

Legendre functions of fractional order exist and follow from insertion of fractional derivatives as defined by fractional calculus and non-integer factorials (defined by the gamma function) into the Rodrigues' formula. The resulting functions continue to satisfy the Legendre differential equation throughout (−1,1), but are no longer regular at the endpoints. The fractional order Legendre function Pn agrees with the associated Legendre polynomial P0
n.

Famous quotes containing the words functions, fractional and/or order:

    Adolescents, for all their self-involvement, are emerging from the self-centeredness of childhood. Their perception of other people has more depth. They are better equipped at appreciating others’ reasons for action, or the basis of others’ emotions. But this maturity functions in a piecemeal fashion. They show more understanding of their friends, but not of their teachers.
    Terri Apter (20th century)

    Hummingbird
    stay for a fractional sharp
    sweetness, and’s gone, can’t take
    more than that.
    Denise Levertov (b. 1923)

    One serious drawback about letters is that, in order to get them, one must send some out. When it comes to the mail, I feel it is better to receive than to give.
    Joseph Epstein (b. 1937)
