Unstable polarized del Pezzo surfaces

Transactions of the American Mathematical Society. 2019. Vol. 372. No. 10. P. 7255-7296.
Cheltsov I., Martinez-Garcia J.

We provide new examples of -unstable polarized smooth del Pezzo surfaces using a flopped version first used by Cheltsov and Rubinstein of the test configurations introduced by Ross and Thomas. As an application, we provide new obstructions for the existence of constant scalar curvature Kähler metrics on polarized smooth del Pezzo surfaces.
