WebJul 9, 2024 · Note. Equation (6.5.6) is a key equation which occurs when studying problems possessing spherical symmetry. It is an eigenvalue problem for Y(θ, ϕ) = Θ(θ)Φ(ϕ), LY = − λY, where L = 1 sinθ ∂ ∂θ(sinθ ∂ ∂θ) + 1 sin2θ ∂2 ∂ϕ2. The eigenfunctions of this operator are referred to as spherical harmonics. irs box 12a
