边界复形与权滤子

Boundary complexes and weight filtrations

Sam Payne

摘要:

研究了代数簇紧化的对数分解中边界因子的对偶复形,证明了这些复形的同伦类型与所有选择无关。受非阿基米德几何最近发展的启发,我们考虑了这些边界复形与奇异上同调和具有紧支集的上同调的权滤之间的关系,并应用于孤立奇点的对偶复形的分解,推广了Stepanov和Thuillier的结果.

英文摘要:

We study the dual complexes of boundary divisors in log resolutions of compactifications of algebraic varieties and show that the homotopy types of these complexes are independent of all choices. Inspired by recent developments in nonarchimedean geometry, we consider relations between these boundary complexes and weight filtrations on singular cohomology and cohomology with compact supports, and give applications to dual complexes of resolutions of isolated singularities that generalize results of Stepanov and Thuillier.
