Elliptic structures on weighted three-dimensional Fano hypersurfaces

Ivan Cheltsov

We classify birational maps into elliptic fibrations of a general quasismooth hypersurface in $P (1, a_{1}, a_{2}, a_{3}, a_{4})$ of degree $\sum_{i = 1}^{4} a_{i}$ that has termi…

Weighted Fano threefold hypersurfaces

Ivan Cheltsov, Jihun Park

We study birational transformations into elliptic fibrations and birational automorphisms of quasismooth anticanonically embedded weighted Fano 3-fold hypersurfaces having terminal…

On nodal sextic fivefold

Ivan Cheltsov

We prove the birational superrigidity and nonrationality of a hypersurface in $P^{6}$ of degree 6 having at most isolated ordinary double points.

Factorial threefolds and Shokurov vanishing

Ivan Cheltsov

We prove the factoriality of the following nodal threefolds: a complete intersection of hypersurfaces $F$ and $G \subset P^{5}$ of degree $n$ and $k$ respectively, where $G$ …
