Recently, Kento Fujita and Yuji Odaka introduced delta-invariant of Fano varieties. It plays an important role in K-stability similar to alpha-invariant introduced by Tian many years ago. Delta-invariant is more powerful than alpha-invariant. But it is also much harder to compute it. In my talk I will show how to estimate delta-invariants for some smooth del Pezzo surfaces.

This seminar gives an introduction to this week's "QGM seminar". The seminar is meant for Master and PhD students - all are welcome.
