No group theory, but the proof by induction does qualify as an "elementary proof", since it only uses the recurrence formula for the Legendre …
A third definition is in terms of solutions to Legendre's differential equation: This differential equation has regular singular points at x = ±1 so if a solution is sought using the standard Frobenius or power series method, a series about the origin will only converge for x < 1 in general. When n is an integer, the solution Pn(x) that is regular at x = 1 is also regular at x = −1, and the series for this solution terminates (i.e. it is a polynomial). The orthogonality and complet…
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 … Se mer 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. Se mer 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 Se mer The complex spherical harmonics $${\displaystyle Y_{\ell }^{m}}$$ give rise to the solid harmonics by extending from $${\displaystyle S^{2}}$$ to all of $${\displaystyle \mathbb {R} ^{3}}$$ as a homogeneous function of degree $${\displaystyle \ell }$$, … Se mer The spherical harmonics have deep and consequential properties under the operations of spatial inversion (parity) and rotation. Parity Se mer Spherical harmonics were first investigated in connection with the Newtonian potential of Newton's law of universal gravitation in … Se mer Orthogonality and normalization Several different normalizations are in common use for the Laplace spherical harmonic functions Se mer 1. When $${\displaystyle m=0}$$, the spherical harmonics $${\displaystyle Y_{\ell }^{m}:S^{2}\to \mathbb {C} }$$ reduce to the ordinary Legendre polynomials: Y ℓ 0 ( θ , φ ) = 2 ℓ + 1 4 π P ℓ ( cos θ ) . {\displaystyle Y_{\ell }^{0}(\theta ,\varphi )={\sqrt {\frac {2\ell … Se mer don\u0027t worry darling imdb ratingNettetIntroduction¶.
