模的有限滤子与可壳多重复形
Finite Filtrations of Modules and Shellable Multicomplexes
摘要:
我们引入了相当干净的模块,通过Dress扩展了干净模块的概念,并证明了相当干净的模块是顺序的Cohen-Macaulay。我们还将Dress关于可壳单纯复形的一个定理推广到多重复形.
英文摘要:
We introduce pretty clean modules, extending the notion of clean modules by Dress, and show that pretty clean modules are sequentially Cohen-Macaulay. We also extend a theorem of Dress on shellable simplicial complexes to multicomplexes.
