Special cases include, The above illustrations show normally used in physics, as described by Arfken (1985) and the Wolfram Associated polynomials are sometimes called Ferrers' functions (Sansone 1991, p. 246). In special functions, a topic in mathematics, spin-weighted spherical harmonics are generalizations of the standard spherical harmonics and—like the usual spherical harmonics—are functions on the sphere.Unlike ordinary spherical harmonics, the spin-weighted harmonics are U(1) gauge fields rather than scalar fields: mathematically, they take values in a complex line bundle.
