Algorithms to compute chern-schwartz-macpherson and segre classes and the euler characteristic

Let V be a closed subscheme of a projective space P n . We give an algorithm to compute the Chern-Schwartz-MacPherson class, and the Euler characteristic of V and an algorithm to compute the Segre class of V. The algorithms can be implemented using ...

Let V be a possibly singular scheme-theoretic global complete intersection subscheme of Pⁿ and assume that V can be written as the intersection of j hypersurfaces such that the intersection of j -- 1 of the hypersurfaces is smooth (scheme theoretically)...
