A K-theoretic Classification of Totally Real Immersions into C
Totally real immersions of an n-dimensional smooth manifold M into C exist, provided that the complexified tangent bundle of M is trivial. A bijection between the set of isotopy classes of such immersions and the complex K-group K(M) is constructed. Gromov [4] and Lees [7] have given a homotopy classification of totally real and Lagrangian immersions into complex and symplectic manifolds. Our a...
متن کاملImmersions of Non-orientable Surfaces
Let F be a closed non-orientable surface. We classify all finite order invariants of immersions of F into R, with values in any Abelian group. We show they are all functions of the universal order 1 invariant that we construct as T ⊕ P ⊕Q where T is a Z valued invariant reflecting the number of triple points of the immersion, and P,Q are Z/2 valued invariants characterized by the property that ...
متن کاملTotally umbilical radical transversal lightlike hypersurfaces of Kähler-Norden manifolds of constant totally real sectional curvatures
In this paper we study curvature properties of semi - symmetric type of totally umbilical radical transversal lightlike hypersurfaces $(M,g)$ and $(M,widetilde g)$ of a K"ahler-Norden manifold $(overline M,overline J,overline g,overline { widetilde g})$ of constant totally real sectional curvatures $overline nu$ and $overline {widetilde nu}$ ($g$ and $widetilde g$ are the induced metrics on $M$...
متن کاملComplementary Regions for Immersions of Surfaces
Let F be a closed surface and i : F → S a generic immersions. Then S− i(F ) is a union of connected regions, which may be separated into two sets {Uj} and {Vj} by a checkerboard coloring. For k ≥ 0 let ak, bk be the number of components Uj , Vj with χ(Uj) = 1 − k, χ(Vj) = 1 − k, respectively. Two more integers attached to i are the number N of triple points of i, and χ = χ(F ). In this work we ...
متن کاملImmersions of Surfaces into Aspherical 3-manifolds
We study finite order invariants of null-homotopic immersions of a closed orientable surface into an aspherical orientable 3-manifold. We give the foundational constructions, and classify all order one invariants.
