Abstract

We prove that the alpha invariant of a quasi-smooth Fano 3-fold weighted hypersurface of index is greater than or equal to. Combining this with the result of Stibitz and Zhuang [SZ19] on a relation between birational superrigidity and K-stability, we prove the K-stability of a birationally superrigid quasi-smooth Fano 3-fold weighted hypersurfaces of index.
