Modification Systems and Integration in Their Chow Groups
نویسنده
چکیده
We introduce a notion of integration on the category of proper birational maps to a given variety X, with value in an associated Chow group. Applications include new birational invariants; comparison results for Chern classes and numbers of nonsingular birational varieties; ‘stringy’ Chern classes of singular varieties; and a zeta function specializing to the topological zeta function. In its simplest manifestation, the integral gives a new expression for ChernSchwartz-MacPherson classes of possibly singular varieties, placing them into a context in which a ‘change-of-variable’ formula holds.

متن کاملA novel modification of decouple scaled boundary finite element method in fracture mechanics problems
In fracture mechanics and failure analysis, cracked media energy and consequently stress intensity factors (SIFs) play a crucial and significant role. Based on linear elastic fracture mechanics (LEFM), the SIFs and energy of cracked media may be estimated. This study presents the novel modification of decoupled scaled boundary finite element method (DSBFEM) to model cracked media. In this metho...
