Sur le comportement asymptotique des oscillations linéaires du modèle homogène compressible
P. Iweins, Paul Smeyers · Bulletin de la Classe des sciences · 1968
Asymptotic expressions are given for the eigenvalues and for the eigenfunctions [formula] associated to the p-modes and to the g-modes of the homogeneous compressible sphere. The first approximation of Langer's asymptotic method gives a good agreement with the exact eigenvalues.
