Delta-invariant for projective bundles over a curve and K-semistability

Houari Benammar Ammar, Louis Massonnet, Chenxi Yin

Consider $E$ a vector bundle over a smooth curve $C$. We compute the $\delta$-invariant of all ample ($\mathbb{Q}$-) line bundles on $\mathbb{P}(E)$ when $E$ is strictly Mumford semista…
