Cohomology characters on the incidence correspondence

Annet Kyomuhangi, Emanuela Marangone, Claudiu Raicu +1

We investigate the cohomology of line bundles on the incidence correspondence, the partial flag variety parametrizing pairs consisting of a point in projective space and a hyperpla…

The effective Chen ranks conjecture

Marian Aprodu, Gavril Farkas, Claudiu Raicu +1

Koszul modules and their associated resonance schemes are objects appearing in a variety of contexts in algebraic geometry, topology, and combinatorics. We present a proof of an ef…

Computing the cohomology of line bundles on the incidence correspondence and related invariants

Annet Kyomuhangi, Emanuela Marangone, Claudiu Raicu +1

We describe the package "IncidenceCorrespondenceCohomology" for the computer algebra system Macaulay2. The main feature concerns the computation of characters and dimensions for th…

Cohomology on the incidence correspondence and related questions

Annet Kyomuhangi, Emanuela Marangone, Claudiu Raicu +1

We study a variety of questions centered around the computation of cohomology of line bundles on the incidence correspondence (the partial flag variety parametrizing pairs consisti…

Some questions arising from the study of cohomology on flag varieties

Zhao Gao, Claudiu Raicu, Keller VandeBogert

A fundamental problem at the confluence of algebraic geometry and representation theory is to describe the cohomology of line bundles on flag varieties over a field of characterist…

Stable sheaf cohomology on flag varieties

Claudiu Raicu, Keller VandeBogert

We prove an effective stabilization result for the sheaf cohomology groups of line bundles on flag varieties parametrizing complete flags in k^n, as well as for the sheaf cohomolog…
