A Secondary Chern-euler Class
Let ξ be a smooth oriented vector bundle, with n-dimensional fibre, over a smooth manifold M . Denote by ξ̂ the fibrewise one-point compactification of ξ. The main purpose of this paper is to define geometrically a canonical element Υ(ξ) in H(ξ̂,Q) (H(ξ̂,Z) ⊗ 12 , to be more precise). The element Υ(ξ) is a secondary characteristic class to the Euler class in the fashion of Chern-Simons. Two proper...
متن کاملSecondary Chern-euler Class for General Submanifold
We define and study the secondary Chern-Euler class for a general submanifold of a Riemannian manifold. Using this class, we define and study index for a vector field with non-isolated singularities on a submanifold. As an application, our studies give conceptual proofs of a classical result of Chern. The objective of this paper is to define, study and use the secondary Chern-Euler class for a ...
متن کاملOn Sha’s Secondary Chern-euler Class
In the spirit of Chern’s proof of the Gauss-Bonnet theorem, we show that Sha’s secondary Chern-Euler form Ψ is exact away from the outward and inward unit normal vectors by constructing a form Γ such that dΓ = Ψ. Using Stokes’ theorem, this evaluates the boundary term α∗(Ψ)[M ] in Sha’s relative Poincaré-Hopf theorem in terms of more classical local indices, Ind ∂+V and Ind ∂−V , for the tangen...
متن کاملThe Law of Vector Fields
When I was 13, the intellectual world began opening up to me. I remember discussing with my friends the list of Sciences which we were soon to be offered. There was Chemistry, Biology, Geology, Astronomy, and Physics. We knew what Chemistry was. It was the study of Chemicals. Biology was the study of life, Geology studied rocks and Astronomy the stars and planets. But what was Physics ? Now, ma...
متن کاملChern Classes of Logarithmic Vector Fields
Let X be a nonsingular complex variety and D a reduced effective divisor in X. In this paper we study the conditions under which the formula cSM (1U ) = c(DerX(− logD)) ∩ [X] is true. We prove that this formula is equivalent to a RiemannRoch type of formula. As a corollary, we show that over a surface, the formula is true if and only if the Milnor number equals the Tjurina number at each singul...
