报告题目: n-cluster tilting subcategories and localizations on extriangulated categories


报告摘要:In this talk, we define and study n-cluster tilting subcategories on an exact category and a triangulated category in a unified method, by means of the notion of an extriangulated category. It gives rise to a family of abelian quotient categories, which are called "hearts". We show these hearts are equivalent to the category of coherent functors over the "coheart" of n-cluster tilting subcategory modulo projective objects.  We also talk about localizations on an extriangulated category.
