Locally stable degenerations of log Calabi-Yau pairs

Time：Thur.,15:30-16:30, Jun. 8, 2023

Venue：Zoom ID: 455 260 1552; PW: YMSC

Organizer：Caucher Birkar，曲三太，陈炳仪

Speaker：Junpeng Jiao 焦骏鹏 Tsinghua University

Abstract

We study the birational boundedness of special fibers of log Calabi-Yau fibrations and Fano fibrations. We show that for a locally stable family of Fano varieties or polarised log Calabi-Yau pairs over a curve, if the general fiber satisfies some natural boundedness conditions, then every irreducible component of the special fiber is birationally bounded.

Algebraic Geometry Seminar | Birational modifications of elliptic Calabi-Yau degenerations
Abstract:In this talk, upon discussing aspects of the string landscape, I will motivate and introduce a program for birationally characterizing the infinite-distance degenerations of compact elliptic Calabi-Yau varieties, described in a Weierstrass form. Then, I will report on our main results for elliptic K3 surfaces, which conform with what is known about Kulikov models. If time permits, a re...
