  • Ticket #25034 – Description

    v7 v37  
     1The current implementation of `gen_legendre_P` is not accurate. No distinction between Ferrers functions and Legendre functions has been made and some special cases are not correctly implemented. This heavily affects spherical harmonics. For a quick fix, to make spherical harmonics work, I propose to temporarily restrict `gen_legendre_P` to Ferrers functions. In a follow-up #31637, we will make the distinction complete.

    28from `sage/functions/orthogonal_polys.py`) to evaluate associated Legendre
