Abstract |
Let f : M → Rp be a special generic
map of a closed n-dimensional manifold M
with n ≥ p ≥ 1. We study the condition for
f to be factorized as f = π ο η
for an immersion (or an embedding) η : M →
Rn+1 and an orthogonal projection π : Rn+1
→ Rp. For various dimension pairs (n,p)
we give answers to such a lifting problem.
In particular, for the cases where p is equal to 1 and 2
we obtain complete results.
