A new approach to projectivity in the categories of complexes, II

Driss Bennis, Juan Ramón García Rozas, Hanane Ouberka, Luis Oyonarte

摘要:

模的次投射性为经典投射性和平坦性提供了一个新的统一框架。在本文中,我们通过推广和统一几个已知的经典结果,将这一事实推广到复形范畴。我们还提供了各种例子来说明所建立的结果的范围和限制。本文是最近工作的延续,其中除其他几件事外,证明了复形的次投射性可以用同伦范畴中的态射来表征。

英文摘要:

It is now very known how the subprojectivity of modules provides a fruitful new unified framework of the classical projectivity and flatness. In this paper, we extend this fact to the category of complexes by generalizing and unifying several known classical results. We further provide various examples to illustrate the scopes and limits of the established results. This paper is a continuation of a recent work in which it was shown among other several things that the subprojectivity of complexes can be characterized in terms of morphisms in the homotopy category.
