Valuative invariants with higher moments

Kewei Zhang

In this article we introduce a family of valuative invariants defined in terms of the $p$ -th moment of the expected vanishing order. These invariants lie between $α$ and $δ$ -invari…

On the Cheltsov--Rubinstein conjecture

Kento Fujita, Yuchen Liu, Hendrik Süß +2

In this note we investigate the Cheltsov--Rubinstein conjecture. We show that this conjecture does not hold in general and some counterexamples will be presented.

Delta invariants of smooth cubic surfaces

Ivan Cheltsov, Kewei Zhang

We prove that $δ$ -invariants of smooth cubic surfaces are at least $\frac{6}{5}$ .
