Cohomology of flag supervarieties and resolutions of determinantal ideals
Steven V Sam, Andrew Snowden
We study the coherent cohomology of generalized flag supervarieties. Our main observation is that these groups are closely related to the free resolutions of (certain generalizatio…
On some modules supported in the Chow variety
Claudiu Raicu, Steven V Sam, Jerzy Weyman
The study of Chow varieties of decomposable forms lies at the confluence of algebraic geometry, commutative algebra, representation theory and combinatorics. There are many open qu…
Hermite reciprocity and Schwarzenberger bundles
Claudiu Raicu, Steven V Sam
Hermite reciprocity refers to a series of natural isomorphisms involving compositions of symmetric, exterior, and divided powers of the standard -representation. We survey se…
A Bruhat atlas for the Mehta-van der Kallen stratification of
Allen Knutson, Steven V Sam
Mehta and van der Kallen put a Frobenius splitting on the type A cotangent bundle , thereby defining a stratification by compatibly split subvarieties, and they determi…
On the geometry and representation theory of isomeric matrices
Rohit Nagpal, Steven V Sam, Andrew Snowden
The space of complex matrices can be regarded as an algebraic variety on which the group acts. There is a rich interaction between geome…
