Bio: Junyi Xie is a Professor at Beijing International Center for Mathematical Research, Peking University. He received Licence 3 and Master from École Normale Supérieure and Paris 7 in 2011, and PhD from Centre de mathématiques Laurent Schwartz de École Polytechnique. He was a full researcher at CNRS from 2016 to 2021. Also, he had postdoc experiences at the University of Rennes 1 and the Institute of Mathematics of Toulouse. The main research interests of Junyi Xie lie in arithmetic dynamics and related questions in algebraic geometry.

The geometric Bombieri-Lang conjecture for varieties of maximal Albanese dimension.

This is a joint work with Xinyi Yuan. Let K=k(B) the function field a variety B over a field k of characteristic 0. Let X be a projective variety over K. Assume that there is a finite morphism from X to an abelian variety A with trivial trace. We show that X(K) is contained in the algebraic special subset. In particular, if further X is of general type, then X(K) is not Zariski dense.

Bio: Konstantin Loginov graduated from the Faculty of Mathematics and Mechanics of Lomonosov Moscow State University in 2015. He obtained PhD in the Department of Mathematics of the Higher School of Economics in Moscow in 2020. He was a scientific researcher in the Laboratory of Algebraic Geometry of the Higher School of Economics. Now he is a scientific researcher in the Department of Algebraic Geometry of Steklov Mathematical Institute and in the Moscow Institute of Physics and Technology. His research interests include algebraic geometry, especially birational geometry.

Coregularity of smooth Fano threefolds.

Fano varieties are an important class of varieties studied in birational geometry. A natural way to study Fano varieties is by looking at its (pluri-)anti-canonical divisors. Coregularity measures how singular such divisors could be. We explain how to compute the coregularity of smooth Fano varieties of dimension 3.

 The meeting will be held in the form of a webinar on the Zoom platform.

Pre-registration for the event is not required.
