We show that general one-nodal prime Fano threefolds of genus $12$ are K-polystable.
In this article, we compute $δ$-invariants of Du Val del Pezzo surfaces of degree $\ge 4$.
In this article, we compute $δ$-invariant of Du Val del Pezzo surfaces of degree $3$.
In this article, we compute $δ$-invariants of Du Val del Pezzo surfaces of degree 2.
In this article, we compute $δ$-invariants of Du Val del Pezzo surfaces of degree 1.
We compute the $δ$-invariant for pairs $(\mathbb{P}^2, λC_d)$, where $C_d$ is a plane curve of degree $d \leq 4$. These computations provide new examples of $K$-stable and $K$-semistable log Fano pairs, and contribute to the study of $K$-stability of log Fano varieties via the Abban-Zhuang method, which reduces higher-dimensional problems to the surface case.
We prove K-stability of smooth Fano 3-folds of Picard rank 3 and degree 20 that satisfy very explicit generality condition.
We prove that all smooth Fano threefolds in the families 2.1, 2.2, 2.3, 2.4, 2.6 and 2.7 are K-stable, and we also prove that smooth Fano threefolds in the family 2.5 that satisfy one very explicit generality condition are K-stable.
By identifying K-polystable limits in 4 specific deformations families of smooth Fano 3-folds, we complete the classification of one-dimensional components in the K-moduli space of smoothable Fano 3-folds.
We find all K-polystable smooth Fano threefolds that can be obtained as blowup of projective space along the disjoint union of a twisted cubic curve and a line.
