上链微分分次代数的同调性质

Homological properties of cochain Differential Graded algebras

Anders J. Frankild, Peter Jorgensen

摘要:

考虑一个局部链微分分次代数,例如一个路径连通拓扑群的奇异链复形。在以前的两篇论文中,证明了这样一个代数的一些同调结果:振幅不等式,Auslander-Buchsbaum等式和间隙定理。这些都是受到同调环论的启发。通过所谓的“镜子原理”,人们可以预期对于单连通上链微分分次代数也存在类似的结果,例如单连通拓扑空间的奇异上链复形。事实上,本文建立了类似的结果。

英文摘要:

Consider a local chain Differential Graded algebra, such as the singular chain complex of a pathwise connected topological group. In two previous papers, a number of homological results were proved for such an algebra: An Amplitude Inequality, an Auslander-Buchsbaum Equality, and a Gap Theorem. These were inspired by homological ring theory. By the so-called looking glass principle, one would expect that analogous results exist for simply connected cochain Differential Graded algebras, such as the singular cochain complex of a simply connected topological space. Indeed, this paper establishes such analogous results.
