Gorenstein modifications and -Gorenstein rings
Hailong Dao, Osamu Iyama, Ryo Takahashi +1
Let be a Cohen--Macaulay normal domain with a canonical module . It is proved that if admits a noncommutative crepant resolution (NCCR), then necessarily it is $\mathb…
Noncommutative resolutions using syzygies
Hailong Dao, Osamu Iyama, Srikanth B. Iyengar +3
Given a noether algebra with a noncommutative resolution, a general construction of new noncommutative resolutions is given. As an application, it is proved that any finite length…
Finite F-type and F-abundant modules
Hailong Dao, Tony Se
In this note we introduce and study basic properties of two types of modules over a commutative noetherian ring of positive prime characteristic. The first is the category of m…
Cohomological support and the geometric join
Hailong Dao, William Sanders
Let be finitely generated modules over a local complete intersection . Assume that for each , . We prove that the cohomological support of $M…
On the associated primes of local cohomology
Hailong Dao, Pham Hung Quy
Let be a commutative Noetherian ring of prime characteristic . In this paper we give a short proof using filter regular sequences that the set of associated prime ideals of…
