Hereditary cotorsion pairs and silting subcategories in extriangulated categories
Published 17 Aug 2021 in math.RT | (2108.07773v2)
Abstract: In this paper, we study (complete) cotorsion pairs in extriangulated categories. First, we study a relationship between an interval of the poset of cotorsion pairs and the poset of cotorsion pairs in the heart associated to the interval. Secondly, we establish a bijection between bounded hereditary cotorsion pairs and silting subcategories in extriangulated categories.
