Birational automorphisms and movable cone of Calabi-Yau complete intersections

Abstract: In 2013 Cantat and Oguiso used Coxeter groups to calculate the birational automorphism group and prove the Kawamata-Morrison conjecture for varieties of Wehler type. In this talk, we use generalized geometric representations of Coxeter groups to compute the movable cone and to extend Cantat-Oguiso's result to Calabi-Yau complete intersections in products of projective spaces.

American Graduate Student Algebraic Geometry Seminar

Series comments: The American Graduate Student Algebraic Geometry Seminar (AGSAGS) is a virtual seminar by and for algebraic geometry graduate students.

The goal of this seminar is for graduate students to share their research through online talks and to provide an algebraic geometry graduate networking system. Grad students, postdocs, and professors are welcome to attend.

Seminars will be held on Mondays at 4 p.m. Eastern on Zoom. We hope this time is convenient for graduate students in the Americas, hence the name AGSAGS. Prior registration is required and interested participants should register here: sites.google.com/view/agsags/registration. In addition to graduate talks, there will be occasional social events.
