Webhypersurface with a fixed class in the Picard group of X. 1 Introduction Let X be a compact algebraic variety over C. We are interested by the following problem: Let V1,...,V N be a collection of germs of smooth analytic hypersurfaces at pairwise distincts smooth points p1,...,p N of X, and fix α in the Picard group Pic(X) of X. WebJul 10, 1996 · We prove a simple formula for MacPherson's Chern class of hypersurfaces in nonsingular varieties. The result highlights the relation between MacPherson's class and other definitions of homology Chern classes of singular varieties, such as Mather's Chern class and a class introduced by W. Fulton.
