Generalized binomial edge ideals are Cartwright-Sturmfels
Aldo Conca, Emanuela De Negri, Volkmar Welker
Binomial edge ideals associated to a simple graph G were introduced by Herzog and collaborators and, independently, by Ohtani. They became an ``instant classic" in combinatorial co…
Lifting Frobenius splittings through geometric vertex decomposition
Emanuela De Negri, Elisa Gorla, Patricia Klein +2
Frobenius splitting, pioneered by Hochster and Roberts in the 1970s and Mehta and Ramanathan in the 1980s, is a technique in characteristic commutative algebra and algebraic ge…
Invariants of toric double determinantal rings
Jennifer Biermann, Emanuela De Negri, Oleksandra Gasanova +2
We study a class of double determinantal ideals denoted , which are generated by minors of size 2, and show that they are equal to the Hibi rings of certain finite distri…
Retrieving biparameter persistence modules from monoparameter ones: a characterization of hook-decomposable persistence modules
Isabella Mastroianni, Marco Guerra, Ulderico Fugacci +1
Motivated by the need to relate the biparameter persistence module induced by a pair of scalar functions with the monoparameter persistence modules induced by each function separat…
Radical support for multigraded ideals
Aldo Conca, Emanuela De Negri, Elisa Gorla
Can one tell if an ideal is radical just by looking at the degrees of the generators? In general, this is hopeless. However, there are special collections of degrees in multigraded…
Invariants of ideals generated by pfaffians
Emanuela De Negri, Elisa Gorla
Ideals generated by pfaffians are of interest in commutative algebra and algebraic geometry, as well as in combinatorics. In this article we compute multiplicity and Castelnuovo-Mu…
