Three takes on almost complete intersection ideals of grade 3

Commutative Algebra 2021-06-29 v1

Abstract

We are interested in the structure of almost complete intersection ideals of grade 3. We give three constructions of these ideals and their free resolutions: one from the commutative algebra point of view, an equivariant construction giving a nice canonical form, andfinally an interpretation in terms of open sets in certain Schubert varieties.
