On the Role of the Double Fourier Sphere Method in Fast Algorithms on SO(3)

arXiv:2602.06677v2 Announce Type: replace Abstract: We analyze the Double Fourier Sphere (DFS) method on the rotation group $\mathcal{SO}(3)$ in the frequency domain and demonstrate its central role in fast algorithms. Fast Fourier algorithms on $\mathcal{SO}(3)$ are commonly ...
