A note on degenerations of del Pezzo surfaces
Annales de l'Institut Fourier, Volume 65 (2015) no. 1, pp. 369-388.

We prove that for a Q-Gorenstein degeneration X of del Pezzo surfaces, the number of non-Du Val singularities is at most ρ(X)+2. Degenerations with ρ(X)+2 and ρ(X)+1 non-Du Val points are investigated

Nous montrons que pour une dégénérescence Q-Gorenstein X de surfaces de del Pezzo, le nombre de singularités non-Du Val est au plus ρ(X)+2. Les dégénérescences avec ρ(X)+2 et ρ(X)+1 points non-Du Val sont étudiées.
