Webwhich relates the Legendre polynomials to the spherical harmonics with m = 0. In terms of the spherical harmonics, the general solution to Laplace’s equation can be written as: T(r,θ,φ) = X∞ ℓ=0 Xℓ m=−ℓ (aℓmr ℓ +b ℓmr −ℓ−1)Ym ℓ (θ,φ). In particular, ∇~2 (aℓmrℓ +bℓmr −ℓ 1)Ym ℓ (θ,φ) = 0. WebIt is seen that both the spherical Bessel functions oscillate and decay as ρ → ∞.
