Workshop Series on Non-Archimedean and Tropical Geometry
ZoomThe Workshop Non-Archimedean and Tropical Geometry, originally planned for Fall 2020, has been converted to a series of smaller virtual (and later hybrid) afternoon workshops to take place biweekly in the Fall of 2021. The first session will take place on Friday, October 1st, 2021. Later sessions, starting on Nov. 12, will take place in a … Continue reading Workshop Series on Non-Archimedean and Tropical Geometry

Grigory Andreychev (Universität Bonn): Descent on Analytic Adic Spaces via Condensed Mathematics
Heidelberg, Mathematikon, SR A and LivestreamIn this talk, I am going to explain the main results of my recent preprint (arXiv:2105.12591). The primary goal will be to prove that for every affinoid analytic adic space $X$, pseudocoherent complexes, perfect complexes, and finite projective modules over $\mathcal{O}_X(X)$ form a stack with respect to the analytic topology on $X$. The proof relies on the new approach to analytic geometry developed by Clausen and Scholze by means of condensed mathematics; therefore, I will also explain how to apply their formalism of condensed analytic rings to the study of adic geometry.
