We study sup-norms of sections of metrized line bundles for families of arithmetic varieties. Using Riemann-Zariski spaces we obtain formulas that imply new definability results in the context of globally valued fields. I will outline our setup and motivations.    Simonyi Hall 101 a7a99c3d46944b65a08073518d638c23

Add to calendar 03/12/2026 12:00 03/12/2026 13:00 Workshop on Recent Developments in Hodge Theory and O-minimality use-title Topic: On the Completions of General Period Mappings Speakers: Haohua Deng, Dartmouth College More: https://www.ias.edu/math/events/workshop-recent-developments-hodge-theory-and-o-minimality-13 Abstract: Constructing completions of period mappings with significant geometric and Hodge-theoretical meaning is an important topic in Hodge theory and its applications. There are rich theories for the classical case in which the period domain is Hermitian symmetric. In this talk I will talk about recent breakthroughs in the non-classical settings, particularly the generalized toroidal completion in the sense of Ash--Mumford--Raport--Tai and Kato--Nakayama--Usui. Joint works with Colleen Robles and Jacob Tsimerman. Simonyi Hall 101 a7a99c3d46944b65a08073518d638c23
