| Résumé : | Let Sm be an embedding of PG(m,q) into PG(n,qr),with n < m, such that Sm generates PG(n,qr). Sm can be obtained as a projection from a (m-n-1)-dimensional subspace Vm-n-1 into a non incident n-dimensional subspace Vn of some strong embedding S of PG(m,q) into PG(m,qr). © 1981 Birkhäuser Verlag. |
