Noether-Fano Inequalities and Canonical Thresholds on Fano Varieties

Charlie Stibitz

We prove a more general and precise version of the Noether-Fano inequalities for birational maps between Mori fiber spaces. This is applied to give descriptions of global canonical…

K-stability of birationally superrigid Fano varieties

Charlie Stibitz, Ziquan Zhuang

We prove that every birationally superrigid Fano variety whose alpha invariant is greater than (resp. no smaller than) $\frac{1}{2}$ is K-stable (resp. K-semistable). We also prove…

Étale Covers and Local Algebraic Fundamental Groups

Charlie Stibitz

Let $X$ be a normal noetherian scheme and $Z \subseteq X$ a closed subset of codimension $\geq 2$ . We consider here the local obstructions to the map $\hatπ_{1}(X\backslash Z) \to…
