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…

Computing epsilon multiplicities in graded algebras
Suprajo Das, Saipriya Dubey, Sudeshna Roy +1
This article investigates the computational aspects of the -multiplicity. Primarily, we show that the -multiplicity of a homogeneous ideal in a two-di…

Computing mixed multiplicities, mixed volumes, and sectional Milnor numbers
Kriti Goel, Vivek Mukundan, Sudeshna Roy +1
This is an expository version of our paper [arXiv:1902.07384]. Our aim is to present recent Macaulay2 algorithms for computation of mixed multiplicities of ideals in a Noetherian r…
