Optimal upper bounds for anti-canonical volumes of singular toric Fano varietiesFix two positive integers d≥3 and q. We give an upper bound for anti-canonical volumes of d-dimensional 1q-lc toric Fano varieties, which corresponds to an upper bound for the dual normalized ...报告人:Yu Zou -

Sheaf stable pairs, Quot-schemes, and birational geometryIn this paper we build bridges between moduli theory of sheaf stable pairs on one hand and birational geometry on the other hand. We will in particular treat moduli of sheaf stable pairs on smooth projective curves in detail and present some calculations in low degrees. We will also outline problems in various directions.报告人:Caucher Birkar, Jia Jia, Artan Sheshmani -

On the cone conjecture for certain pairs of dimension at most 4In this paper, by running MMP and considering the anti-canonical fibration, we prove the Morrison-Kawamata cone conjecture for klt Calabi-Yau pairs (X,Δ) such that dim X is at most 4, and the Iitaka dimension κ(X,−K_X) is at least dimX−2.报告人:Fulin Xu
