Automorphism groups of Inoue and Kodaira surfaces
Yuri Prokhorov, Constantin Shramov
We prove that automorphism groups of Inoue and primary Kodaira surfaces are Jordan.
Delta invariants of singular del Pezzo surfaces
Ivan Cheltsov, Jihun Park, Constantin Shramov
We estimate -invariants of some singular del Pezzo surfaces with quotient singularities, which we studied ten years ago. As a result, we show that each of these surfaces admits…
Automorphisms of pointless surfaces
Constantin Shramov, Vadim Vologodsky
For a geometrically rational surface X over an arbitrary field of characteristic different from 2 and 3 that contains all roots of 1, we show that either X is birational to a produ…
Kaehler-Einstein Fano threefolds of degree 22
Ivan Cheltsov, Constantin Shramov
We study the problem of existence of Kähler--Einstein metrics on smooth Fano threefolds of Picard rank one and anticanonical degree that admit a faithful action of the multipl…
Hodge level for weighted complete intersections
Victor Przyjalkowski, Constantin Shramov
We give lower bounds for Hodge numbers of smooth well formed Fano weighted complete intersections. In particular, we compute their Hodge level, that is, the maximal distance betwee…
