Products, Homotopy Limits and Applications
Amit Hogadi, Chenyang Xu
In this note, we discuss the derived functors of infinite products and homotopy limits. , the category of quasi-coherent sheaves on a Deligne-Mumford stack , usually has…
Fano Varieties with Large Degree Endomorphisms
János Kollár, Chenyang Xu
We give examples of Fano varieties with Picard number 1, which have terminal singularities and admit endomorphisms with degree larger than 1.
On Effective log Iitaka Fibration for 3-folds and 4-folds
Gueorgui Todorov, Chenyang Xu
We prove the effectiveness of the log Iitaka fibration in Kodaira codimension two for varieties of dimension. In particular, we finish the proof of effective log Iitaka fibr…
Congruence for rational points over finite fields and coniveau over local fields
Hélène Esnault, Chenyang Xu
If the -adic cohomology of a projective smooth variety, defined over a local field with finite residue field , is supported in codimension , then every model ov…
