Canonical Stretched Rings
Nguyen Thi Anh Hang , Do Van Kien , Hoang Le Truongpp. 161-179
Abstract
In this paper, we introduce the concept of canonical stretched rings, sparse stretched rings, and maximum sparse ideals. Then, we give characterizations of canonical stretched rings and sparse stretched rings, and a characterization of Gorenstein rings in terms of their maximum sparse ideals. Several explicit examples are provided along the paper to illustrate such rings.
