K-stability of Fano threefolds of rank 3 and degree 14

Grigory Belousov, Konstantin Loginov

We prove that all general smooth Fano threefolds of Picard rank $3$ and degree $14$ are K-stable, where the generality condition is stated explicitly.

Del Pezzo surfaces with four log terminal singularities

Grigory Belousov, DongSeon Hwang

We classify del Pezzo surfaces with Picard number is equal to one and with four log terminal singular points.

Cylinders in del Pezzo surfaces with du Val singularities

Grigory Belousov, Nivedita Viswanathan

We consider del Pezzo surfaces $X$ with du Val singularities. Assume that $X$ has a $- K_{X}$ -polar cylinder and $A^° X = 1$ . Let $H$ be an ample divisor. We'll prove that $X$ has a $H$ -p…

Real del Pezzo surfaces without points

Grigory Belousov

We consider a real del Pezzo surface without points. We prove that the same surface over complex numbers field $C$ has Picard number is at least two.
