Semidualizing modules of ladder determinantal rings
Sean K. Sather-Wagstaff, Tony Se, Sandra Spiroff
We continue our study of ladder determinantal rings over a field from the perspective of semidualizing modules. In particular, given a ladder of variables , we show…
Automating the Calculation of Hilbert-Kunz Multiplicities and F-Signatures
Gabriel Johnson, Sandra Spiroff
The Hilbert-Kunz multiplicity and -signature are important invariants for researchers in commutative algebra and algebraic geometry. We provide software, and describe the automa…
Computing The Invariants of Intersection Algebras of Principal Monomial Ideals
Florian Enescu, Sandra Spiroff
We continue the study of intersection algebras of two ideals in a commutative Noetherian ring . In particular, we exploit the semigroup…
On semidualizing modules of ladder determinantal rings
Sean K. Sather-Wagstaff, Tony Se, Sandra Spiroff
We identify all semidualizing modules over certain classes of ladder determinantal rings over a field . Specifically, given a ladder of variables , we show that the…
