 ### Spherical harmonics
 
-The [spherical harmonics](https://en.wikipedia.org/wiki/Spherical_harmonics) are special functions defined on the two-dimensional sphere $S^2$ (embedded in three dimensions). They form an orthonormal basis of the space of square-integrable functions defined on the sphere ($L^2(S^2)$) and are comparable to the harmonic functions defined on a circle/torus. The spherical harmonics are defined as
