Local cohomology with support in generic determinantal ideals
Claudiu Raicu, Jerzy Weyman
For positive integers m >= n >= p, we compute the GL_m x GL_n-equivariant description of the local cohomology modules of the polynomial ring S of functions on the space of m x n ma…
Local cohomology with support in ideals of maximal minors and sub-maximal Pfaffians
Claudiu Raicu, Jerzy Weyman, Emily E. Witt
We compute the GL-equivariant description of the local cohomology modules with support in the ideal of maximal minors of a generic matrix, as well as of those with support in the i…
Products of Young symmetrizers and ideals in the generic tensor algebra
Claudiu Raicu
We describe a formula for computing the product of the Young symmetrizer of a Young tableau with the Young symmetrizer of a subtableau, generalizing the classical quasi-idempotence…
Non-simplicial decompositions of Betti diagrams of complete intersections
Courtney Gibbons, Jack Jeffries, Sarah Mayes +3
We investigate decompositions of Betti diagrams over a polynomial ring within the framework of Boij--Soederberg theory. That is, given a Betti diagram, we decompose it into pure di…
