Immersions of manifolds
Open accessAbstract
Immersions of an m-manifold in an n-manifold, n>m, are classified up to regular homotopy by the homotopy classes of sections of a vector bundle E associated to the tangent bundle of M. When N = Rn , the fibre of E is the Stiefel manifold of m-frames in n-space.

Any noncompact connected orientable 3-manifold immerses in R2+1.
“Any noncompact connected orientable 3-manifold immerses in R 2+1 by the immersion theorem [1], so some restriction is needed.”
From Lorentz spacetimes of constant curvature (2007) · cites this paper as [1]
The Introduction and Theorem 6.3 state that a parallelizable k-manifold immerses in Euclidean space of dimension k+1; Theorem 6.7 concerns compact 3-manifolds immersing in E4. I searched for noncompact orientable 3-manifolds and same-dimensional immersions, but found no passage in our copy establishing the claimed immersion in R³. The E4 results do not contradict it.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
