Infinite-dimensional flats in the space of positive metrics on an ample line bundle

Rémi Reboulet, David Witt Nyström

We show that any continuous positive metric on an ample line bundle L lies at the apex of many infinite-dimensional Mabuchi-flat cones. More precisely, given any bounded graded fil…

The Minimum Principle for Convex Subequations

Julius Ross, David Witt Nyström

A subequation on an open subset $X \subset R^{n}$ is a subset $F$ of the space of $2$ -jets on $X$ with certain properties. A smooth function is said to be $F$ -subharmonic if a…

Coupled Kähler-Einstein metrics

Jakob Hultgren, David Witt Nyström

We propose new types of canonical metrics on Kähler manifolds, called coupled Kähler-Einstein metrics, generalizing Kähler-Einstein metrics. We prove existence and uniqueness resul…

Duality between the pseudoeffective and the movable cone on a projective manifold

David Witt Nyström, Sébastien Boucksom

We prove a conjecture of Boucksom-Demailly-Păun-Peternell, namely that on a projective manifold $X$ the cone of pseudoeffective classes in $H_{R}^{1, 1} (X)$ is dual to the…
