Segre characteristic
Did you know?
In mathematics, the Segre class is a characteristic class used in the study of cones, a generalization of vector bundles. For vector bundles the total Segre class is inverse to the total Chern class, and thus provides equivalent information; the advantage of the Segre class is that it generalizes to more general cones, while the Chern class does not. The Segre class was introduced in the non-singular case by Segre (1953). . In the modern treatment of intersection the… Webj have the same Segre characteristic. Recall that for an eigenvalue of S, its Segre characteristic is the sequence of sizes of the Jordan blocks of Swith eigenvalue in non-increasing order [15]. We denote the Segre characteristic of an eigenvalue by ((;:::;)). It is now im-mediate that Theorem 1 can in general not be used for a structure ...
