G-birationally rigid cubic threefolds

Ivan Cheltsov, Igor Krylov, Sione Ma'u

We classify pairs $(X, G)$ consisting of a (possibly singular) cubic threefold $X \subset P^{4}$ and a finite subgroup $G \subset Aut (X)$ such that $X$ is $G$ -birational…

Pluripotential theory on algebraic curves

Norm Levenberg, Sione Ma'u

In previous works, the second author defined directional Robin constants associated to a compact, nonpolar subset $K$ of an algebraic curve $A$ in $C^{N}$ and related these…

K-stability and space sextic curves of genus three

Ivan Cheltsov, Oliver Li, Sione Ma'u +1

We study Fano threefolds that can be obtained by blowing up the three-dimensional projective space along a smooth curve of degree six and genus three. We produce many new K-stable…
