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. For spin weight , the spin-weighted spherical harmonics become identical to the spherical harmonics.The case of spin weight is important for describing gravitational waves.

MAIN PROGRAM USAGE: The main programs are 'shana' and 'shsyn' for spherical harmonic analysis and synthesis (go from spatial data to spherical harmonic coefficients and vice versa, respectively). Let us first look at a simple example. Visualising the spherical harmonics is a little tricky because they are complex and defined in terms of angular co-ordinates, $(\theta, \phi)$. I will give some examples. Harmonics, with Applications to Problems in Mathematical Physics. Similarly, we will be able to express spin-weighted spherical harmonics directly in terms of quaternions, though with a simple translation to and from standard spherical coordinates. Bull.

Spherical Geometric Applications of Fourier Series and Spherical Harmonics. As for the reason this expansion is usually not stated in the Hilbert space context, I suspect it is largely cultural. Language (in mathematical literature, usually denotes §12.6 and 12.9 in Mathematical Arfken, G. "Spherical Harmonics" and "Integrals of the Products of Three Spherical Harmonics." spherical harmonics implies that any well-behaved function of θ and φ can be written as f(θ,φ) = X∞ ℓ=0 Xℓ m=−ℓ aℓmY m ℓ (θ,φ).
