Hankel determinantal rings have rational singularities
Aldo Conca, Maral Mostafazadehfard, Anurag K. Singh +1
Hankel determinantal rings, i.e., determinantal rings defined by minors of Hankel matrices of indeterminates, arise as homogeneous coordinate rings of higher order secant varieties…
On the diameter of an ideal
Michela Di Marca, Matteo Varbaro
We begin the study of the notion of diameter of an ideal I of a polynomial ring S over a field, an invariant measuring the distance between the minimal primes of I. We provide larg…
Linear syzygies, hyperbolic Coxeter groups and regularity
Alexandru Constantinescu, Thomas Kahle, Matteo Varbaro
We show that the virtual cohomological dimension of a Coxeter group is essentially the regularity of the Stanley--Reisner ring of its nerve. Using this connection between geometric…
