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…
Sextic Double Solids
Ivan Cheltsov, Jihun Park
We prove non-rationality and birational super-rigidity of a Q-factorial double cover X of P^3 ramified along a sextic surface with at most simple double points. We also show that t…
A note on del Pezzo fibrations of degree 1
Jihun Park
We study del Pezzo fibrations of degree 1 with terminal singularities. A connection between singularities on del Pezzo surfaces of degree 1 and Kodaira's classification of elliptic…
Log Canonical Thresholds and Generalized Eckardt Points
Ivan Cheltsov, Jihun Park
Let be a smooth hypersurface of degree in . We prove that the log canonical threshold of is at least . Under the assumption…
Birational maps of del Pezzo fibrations
Jihun Park
In this paper, we study rigidity of nonsingular del Pezzo fibrations over a germ of smooth curve.
