Gibbs polystability of Fano manifolds, stability thresholds and symmetry breaking
Rolf Andreasson, Robert J. Berman, Ludvig Svensson
We extend the probabilistic approach for constructing Kahler-Einstein metrics on log Fano manifolds X - involving random point processes - to the case of non-discrete automorphism…

Canonical heights, periods and the Hurwitz zeta function
Rolf Andreasson, Robert J. Berman
Let (X,D) be a projective log pair over the ring of integers of a number field such that the log canonical line bundle K_(X,D) or its dual -K_(X,D) is relatively ample. We introduc…

Sharp bounds on the height of K-semistable Fano varieties II, the log case
Rolf Andreasson, Robert J. Berman
In our previous work we conjectured - inspired by an algebro-geometric result of Fujita - that the height of an arithmetic Fano variety X of relative dimension is maximal when…
