The constant scalar curvature Kähler condition is very general

Ruadhaí Dervan

Recent work of Trusiani implies that the existence of a constant scalar curvature Kähler metric on a smooth polarised variety with discrete automorphism group is equivalent to uni…

A birational version of K-stability for big classes

Ruadhaí Dervan, Rémi Reboulet

We introduce a theory of uniform K-stability for big line bundles on smooth projective varieties. This extends the existing theory both for varieties with ample line bundles, and f…

The birational geometry of GIT quotients

Ruadhaí Dervan, Rémi Reboulet

Geometric Invariant Theory (GIT) produces quotients of algebraic varieties by reductive groups. If the variety is projective, this quotient depends on a choice of polarisation; by…

Moduli of polarised manifolds via canonical Kähler metrics

Ruadhaí Dervan, Philipp Naumann

We construct a moduli space of polarised manifolds which admit a constant scalar curvature Kähler metric. We show that this space admits a natural Kähler metric.

Stability conditions in geometric invariant theory

Ruadhaí Dervan

We explain how structures analogous to those appearing in the theory of stability conditions on abelian and triangulated categories arise in geometric invariant theory. This leads…

Arcs, stability of pairs and the Mabuchi functional

Ruadhaí Dervan, Rémi Reboulet

We prove various results involving arcs - which generalise test configurations - within the theory of K-stability. Our main result characterises coercivity of the Mabuchi functiona…
