Local cohomology modules supported at determinantal ideals
Gennady Lyubeznik, Anurag K. Singh, Uli Walther
We provide new results on the vanishing of local cohomology modules supported at ideals of minors of matrices over arbitrary commutative Noetherian rings. In the process, we comput…

Local cohomology modules of a smooth Z-algebra have finitely many associated primes
Bhargav Bhatt, Manuel Blickle, Gennady Lyubeznik +2
Let be a commutative Noetherian ring that is a smooth -algebra. For each ideal of and integer , we prove that the local cohomology module has f…
