We introduce and
describe the topology of a family of complete immersed manifolds in ℝN,
having a nice behaviour at infinity, which we call conical type end manifolds.
Our main result states that a complete, non compact immersed manifold in
ℝN, whose limsup of the norm of the second fundamental form times the
intrinsic distance of the manifold to a fixed point is strictly less than 1, as the
distance goes to infinity, is a conical type end manifold. In particular, it
follows that the manifold has finite topology and is properly immersed in
ℝN.
