Generalized spherical harmonics

WebMar 1, 2006 · Summary. We explain in detail how azimuthally anisotropic maps of surface wave phase velocity can be parametrized in terms of generalized spherical harmonic functions, and why this approach is preferable to others; most importantly, generalized spherical harmonics are the only basis functions adequate to describe a tensor field … WebNow we come to some of the most ubiquitous functions in geophysics,used in gravity, geomagnetism and seismology.Spherical harmonics are the Fourier series for the sphere.These functions can are used to build solutions to Laplace’sequation and other differential equations in a spherical setting.
