Delta-invariants of complete intersection log del Pezzo surfaces

Research output: Contribution to journalArticlepeer-review


We show that complete intersection log del Pezzo surfaces with amplitude one in weighted projective spaces are uniformly -stable. As a result, they admit an orbifold Kähler-Einstein metric.
