Some Results Related to Spherical HarmonicsLet ., . ⩾ 2 denotes the set of all homogeneous harmonic polynomials on ℝ. of degree .. A spherical harmonic of degree . is the restriction to . of an element of .. The collection of all spherical harmonics of degree . will be denoted by .. We note that . and . are a complex vector spaces. In addition, these spaces are invariant under rotations.
