The functions are the Legendre polynomials, and they can be derived as a special case of spherical harmonics. Subsequently, in his 1782 memoir, Laplace investigated these coefficients using spherical coordinates to represent the angle γ between x1 and x. (See Applications of Legendre polynomials in physics for a … 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 The spherical harmonics have deep and consequential properties under the operations of spatial inversion (parity) and rotation. Parity 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, See more Orthogonality and normalization Several different normalizations are in common use for the Laplace spherical harmonic functions See more 1.
