外三角范畴中左Frobenius对构造模型结构的一种新方法

A new method to construct model structures from left Frobenius pairs in extriangulated categories

Yajun Ma, Haiyu Liu, Yuxian Geng

摘要:

外三角范畴是由Nakaoka和Palu作为正合范畴和三角范畴的同时推广而引入的。本文首先在一个外三角范畴C上引入左Frobenius对的概念,然后在C中建立Frobenius对与某些余挠对之间的双射对应。作为应用,在一定条件下,利用左Frobenius对建立了一些新的容许模型结构,推广了Hu等人(J. Algebra 551(2020)23-60)的结果.

英文摘要:

Extriangulated categories were introduced by Nakaoka and Palu as a simultaneous generalization of exact categories and triangulated categories. In this paper, we first introduce the concept of left Frobenius pairs on an extriangulated category C, and then establish a bijective correspondence between Frobenius pairs and certain cotorsion pairs in C. As an application, some new admissible model structures are established from left Frobenius pairs under certain conditions, which generalizes a result of Hu et al. (J. Algebra 551 (2020) 23-60).
