Frobenius identities for the volume map on Cohen--Macaulay rings

Karim Alexander Adiprasito, Eric Katz, Ryoshun Oba +2

We study the volume map on Artinian quotients of Cohen-Macaulay algebras in characteristic , and the interaction between it and the action of Frobenius on resolutions. This allo…

Parseval-Rayleigh identities for homogeneous complete intersections

Karim Alexander Adiprasito, Ryoshun Oba, Stavros Argyrios Papadakis +1

We prove, in any positive characteristic, Parseval-Rayleigh identities for the residue map of a homogeneous complete intersection. As an application, we give a conceptual proof of…

Lattice polytopes and semigroup algebras: Generic Lefschetz properties and Parseval-Rayleigh identities

Karim Alexander Adiprasito, Stavros Argyrios Papadakis, Vasiliki Petrotou

We study semigroup algebras associated to lattice polytopes. We begin by generalizing and refining work of Hochster, and describe the volume maps of these algebras, that is, their…

The volume intrinsic to a commutative graded algebra

Karim Alexander Adiprasito, Stavros Argyrios Papadakis, Vasiliki Petrotou

Recent works of the authors have demonstrated the usefulness of considering moduli spaces of Artinian reductions of a given ring when studying standard graded rings and their Lefsc…

The 4-Intersection Unprojection Format

Vasiliki Petrotou

Unprojection theory is a philosophy due to Miles Reid, which becomes a useful tool in algebraic geometry for the construction and the study of new interesting geometric objects suc…

Beyond positivity in Ehrhart Theory

Karim Alexander Adiprasito, Stavros Argyrios Papadakis, Vasiliki Petrotou +1

We study semigroup algebras arising from lattice polytopes, compute their volume polynomials (particularizing work of Hochster), and establish strong Lefschetz properties (generali…

Anisotropy, biased pairings, and the Lefschetz property for pseudomanifolds and cycles

Karim Adiprasito, Stavros Argyrios Papadakis, Vasiliki Petrotou

We prove the hard Lefschetz property for pseudomanifolds and cycles in any characteristic with respect to an appropriate Artinian reduction. The proof is a combination of Adiprasit…

The characteristic 2 anisotropicity of simplicial spheres

Stavros Argyrios Papadakis, Vasiliki Petrotou

Assume D is a simplicial sphere, and k_1 is a field. We say that D is generically anisotropic over k_1 if, for a certain purely transcendental field extension k of k_1, a certain A…

Tom & Jerry triples with an application to Fano 3-folds

Vasiliki Petrotou

Unprojection is a theory due to Reid which constructs more complicated rings starting from simpler data. The idea of unprojection is intended for serial use. Papadakis and Neves de…
