WebUnder a rotation in three-dimensional space, a three-vector transforms ac-cording to V i → V0 i = X3 j=1 R ijV j (1.1) where V i, i = 1,2,3 stand for the x,y,z components of the vector V~ . (Note: this generalizes trivially to rotations in higher dimensional spaces, but we restrict here to three dimensions). Examples, include the position ... WebSpherical harmonics are a set of functions used to represent functions on the surface of the sphere S^2 S 2. They are a higher-dimensional analogy of Fourier series, which form a complete basis for the set of periodic functions of a single variable ( ( functions on the circle S^1). S 1). Spherical harmonics are defined as the eigenfunctions of ...

WebAbstract. We show that, at first order in the angular velocity, the general relativistic description of Rossby-Haurwitz waves (the analogues of r 𝑟 r italic_r waves on a thin shell) can be obtained from the corresponding Newtonian one after a coordinate transformation. As an application, we show that the results recently obtained by Rezzolla and Yoshida …
