Prethick subcateogries of modules and characterizations of local rings
arXiv:1412.8047
Abstract
This paper studies characterizing local rings in terms of homological dimensions. The key tool is the notion of a prethick subcategory which we introduce in this paper. Our methods recover the theorems of Salarian, Sather-Wagstaff and Yassemi.
