Spherical harmonic representation
Spherical harmonics are important in many theoretical and practical applications, including the representation of multipole electrostatic and electromagnetic fields, electron configurations, gravitational fields, geoids, the magnetic fields of planetary bodies and stars, and the cosmic microwave background radiation. See more 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. See more 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 See more The complex spherical harmonics $${\displaystyle Y_{\ell }^{m}}$$ give rise to the solid harmonics by extending from The Herglotz … See more 1. When $${\displaystyle m=0}$$, the spherical harmonics $${\displaystyle Y_{\ell }^{m}:S^{2}\to \mathbb {C} }$$ reduce to the ordinary See more 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 See more 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 See more The spherical harmonics have deep and consequential properties under the operations of spatial inversion (parity) and rotation.
