矩角复形、单项理想和Massey乘积

Moment-angle complexes, monomial ideals, and Massey products

Graham Denham, Alexander I. Suciu

摘要:

每个有限单纯复形K都有一个“矩角”有限CW-复形Z_K;如果K是球面的三角剖分,则Z_K是光滑的紧致流形。在Buchstaber,Panov和Baskakov的工作基础上,我们研究了矩角复形的上同调环,同伦群和三重Massey积,将这些拓扑不变量与基础单纯复形的代数组合学联系起来。应用研究的非正式流形和子空间安排。

英文摘要:

Associated to every finite simplicial complex K there is a "moment-angle" finite CW-complex, Z_K; if K is a triangulation of a sphere, Z_K is a smooth, compact manifold. Building on work of Buchstaber, Panov, and Baskakov, we study the cohomology ring, the homotopy groups, and the triple Massey products of a moment-angle complex, relating these topological invariants to the algebraic combinatorics of the underlying simplicial complex. Applications to the study of non-formal manifolds and subspace arrangements are given.
