Query: Canonical stretched rings   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.
