Cobordism of immersions of surfaces¶in non-orientable 3-manifolds
- 28 Downloads
Some properties of non-orientable 3-manifolds are shown. In particular, for a connected, non-orientable 3-manifold M, the group of cobordism clases of immersions of surfaces in M is isomorphic to a group structure on the set H 2(M,Z/2Z)×H 1(M,Z/2Z)×Z/2Z.
