Abstract

We use the methods introduced by Cheltsov–Rubinstein–Zhang in [CRZ18] to estimate invariants of the seven singular del Pezzo surfaces with quotient singularities studied by Cheltsov–Park–Shramov in [CPS10] that have invariants less than 2/3 . As a result, we verify that each of these surfaces admits an orbifold K¨ahler–Einstein metric.
