Resolutions in factorization categories
Matthew Ballard, Dragos Deliu, David Favero +2
Generalizing Eisenbud's matrix factorizations, we define factorization categories. Following work of Positselski, we define their associated derived categories. We construct specif…

Variation of geometric invariant theory quotients and derived categories
Matthew Ballard, David Favero, Ludmil Katzarkov
We study the relationship between derived categories of factorizations on gauged Landau-Ginzburg models related by variations of the linearization in Geometric Invariant Theory. Un…
