WebThe theory of scalar spherical harmonics of Chap. 4can be generalized to spheres in the q-dimensional space, i.e., from \({\mathbb{S}}^{2} \subset {\mathbb{R}}^{3}\) to \({\mathbb{S}}^{q-1} \subset {\mathbb{R}}^{q}\). Obviously, this leads to a more extensive notation and makes some formulas a bit unwieldy. However, many proofs and the whole … WebMar 1, 1995 · But V^V(A' + c) is almost everywhere positive). On the other hand, K is the scalar curvature of n(n 1)/ K 170. In fact, it should be interesting to prove that to each / we can associate a first spherical harmonic hf and a conformai difFeomorphism (j> Conf(5'"), such that / hf o (f) is the scalar curvature of a metric conformai to go- We do that ...

WebNov 6, 2024 · See here for an example of how to compute spherical harmonics on the 2D grid (theta, phi), and plot the results as a nice surface in 3D. By the way, you will want to compute the surface values over the full range of angle [0,pi] and [0,2*pi], so that your surface does not have a hole at the south pole or a gap along the prime meridian. WebSpherical Harmonics we discussed so far are scalars in nature; they transform as scalars under coordinate transformations.
