Spherical harmonics l 4
Further, spherical harmonics are basis functions for irreducible representations of SO (3), the group of rotations in three dimensions, and thus play a central role in the group theoretic discussion of SO (3). Spherical harmonics originate from solving Laplace's equation in the spherical domains. Zobraziť viac In mathematics and physical science, spherical harmonics are special functions defined on the surface of a sphere. They are often employed in solving partial differential equations in many scientific fields. Zobraziť viac Laplace's equation imposes that the Laplacian of a scalar field f is zero. (Here the scalar field is understood to be complex, i.e. to correspond to a (smooth) function Zobraziť viac The complex spherical harmonics $${\displaystyle Y_{\ell }^{m}}$$ give rise to the solid harmonics by extending from $${\displaystyle S^{2}}$$ to all of The Herglotz … Zobraziť viac 1. When $${\displaystyle m=0}$$, the spherical harmonics $${\displaystyle Y_{\ell }^{m}:S^{2}\to \mathbb {C} }$$ reduce to the … Zobraziť viac Spherical harmonics were first investigated in connection with the Newtonian potential of Newton's law of universal gravitation in three dimensions. In 1782, Pierre-Simon de Laplace had, in his Mécanique Céleste, determined that the gravitational potential Zobraziť viac Orthogonality and normalization Several different normalizations are in common use for the Laplace spherical harmonic functions $${\displaystyle S^{2}\to \mathbb {C} }$$. Throughout the section, we use the standard convention that for Zobraziť viac The spherical harmonics have deep and consequential properties under the operations of spatial inversion (parity) and rotation. Parity Zobraziť viac WebAn important identity is the so-called addition theorem for spherical harmonics: where cosγ = cosθcosθ ′ + sinθsinθ ′ cos(ϕ − ϕ ′). In other words, γ is the angle between the direction (θ, ϕ) and the direction (θ ′, ϕ ′), so cosγ is the dot product of two unit vectors of the form (sinθcosϕ, sinθsinϕ, cosθ).
