Weak Approximation for Cubic Hypersurfaces and Degree 4 del Pezzo Surfaces
Letao Zhang, Zhiyu Tian
In this article we prove the following theorems about weak approximation of smooth cubic hypersurfaces and del Pezzo surfaces of degree 4 defined over global fields. (1) For cubic…
Extension property of semipositive invertible sheaves over a non-archimedean field
Huayi Chen, Atsushi Moriwaki
In this article, we prove an extension property of semipositively metrized ample invertible sheaves on a projective scheme over a complete non-archimedean valued field. As an appli…
Log Kodaira dimension of homogeneous varieties
Michel Brion, De-Qi Zhang
Let be a complex algebraic variety, homogeneous under the action of a complex algebraic group. We show that the log Kodaira dimension of is non-negative if and only if …
Construction of G_2-instantons via twisted connected sums
Grégoire Menet, Johannes Nordström, Henrique N. Sá Earp
We propose a method to construct G_2-instantons over a compact twisted connected sum G_2-manifold, applying a gluing result of Sá Earp and Walpuski to instantons over a pair of 7-m…
Some structure theorems for algebraic groups
Michel Brion
These are extended notes of a course given at Tulane University for the 2015 Clifford Lectures. Their aim is to present structure results for group schemes of finite type over a fi…
Finiteness of fundamental groups
Zhiyu Tian, Chenyang Xu
We show that the finiteness of the fundamental groups of the smooth locus of lower dimensional log Fano pairs would imply the finiteness of the local fundamental group of klt singu…
