Blowup algebras of determinantal ideals in prime characteristic
Alessandro De Stefani, Jonathan Montaño, Luis Núñez-Betancourt
We study when blowup algebras are -split or strongly -regular. Our main focus is on algebras given by symbolic and ordinary powers of ideals of minors of a generic matrix, a…
The Eisenbud-Green-Harris Conjecture
Giulio Caviglia, Alessandro De Stefani, Enrico Sbarra
We survey most of the known results concerning the Eisenbud-Green-Harris Conjecture. Our presentation includes new proofs of several theorems, as well as a unified treatment of man…
A uniform Chevalley theorem for direct summands of polynomial rings in mixed characteristic
Alessandro De Stefani, Eloísa Grifo, Jack Jeffries
We prove an explicit uniform Chevalley theorem for direct summands of graded polynomial rings in mixed characteristic. Our strategy relies on the introduction of a new type of diff…
