Non-reductive geometric invariant theory and Thom polynomials
Gergely Bérczi
We combine recently developed intersection theory for non-reductive geometric invariant theoretic quotients with equivariant localisation to prove a formula for Thom polynomials of…
Variation of Non-reductive Geometric Invariant Theory
Gergely Bérczi, Joshua Jackson, Frances Kirwan
The wall-and-chamber structure of the dependence of the reductive GIT quotient on the choice of linearisation is well known. In this article, we first give a brief survey of recent…
Stratifying quotient stacks and moduli stacks
Gergely Bérczi, Victoria Hoskins, Frances Kirwan
Recent results in geometric invariant theory (GIT) for non-reductive linear algebraic group actions allow us to stratify quotient stacks of the form [X/H], where X is a projective…
Graded linearisations
Gergely Bérczi, Brent Doran, Frances Kirwan
When the action of a reductive group on a projective variety has a suitable linearisation, Mumford's geometric invariant theory (GIT) can be used to construct and study an associat…
