A note on degenerations of del Pezzo surfaces

Yuri Prokhorov

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…

Threefold extremal contractions of types (IC) and (IIB)

Shigefumi Mori, Yuri Prokhorov

Let $(X, C)$ be a germ of a threefold $X$ with terminal singularities along an irreducible reduced complete curve $C$ with a contraction $f : (X, C) \to (Z, o)$ such that $C=f^{-1}(o)_{…

G-Fano threefolds, II

Yuri Prokhorov

We classify Fano threefolds with only Gorenstein terminal singularities and Picard number greater than 1 satisfying an additional assumption that the $G$ -invariant part of the Weil…
