Upcoming events in 2026

Several events of next year are already planned. More information will appear here in due time.

- The winter colloquium will take place in Berlin on January 29 and 30. It will consist of a new edition of the Northern Algebraic Geometry Seminar (NoGAGS), and be closed with a talk by A. Skorobogatov in the MATH+ colloquium.

- The spring colloquium will be the special section on algebraic geometry during the special onference "Riemann 200" in Hannover, on March 16-18.

- The first women's conference of the RTG will take place in Berlin in May 27-29. More information under this link.

- The next summer school, with title "Moduli of curves, abelian varieties and K3 surfaces", will be part of the Simons Semester in Algebraic Geometry in Budapest. More precisely, it will take place on August 24-28, with lectures by L. Caporaso, P. Engel, R. Pandharipande and A. Pixton.

Open positions

We have open PhD positions to start on October 2026 or sooner. More information can be found here.

First Summer School in Padova (Italy)

We just had the first Summer School of our RTG, with the collaboration of Daniel Litt, Isabel Vogt and Olivier Wittenberg. More information can be found here.

The program started on October 1, 2024, and will run in its first phase through September 30, 2029. It will be hosted by Leibniz Universität Hannover (LUH) and Humboldt-Universität zu Berlin (HU).

The RTG focuses on the fascinating connections between geometry and numbers. The goal is to uncover, describe, and understand new geometric objects and shapes that cannot be visualized — often neither by humans nor by computers. These shapes are frequently described by algebraic equations, some of which play an important role in theoretical physics. Even if the algebraic equations appear simple, the important geometric properties of the corresponding solution sets are often unknown. The goal of the RTG is to understand these solution sets and reveal the beautiful underlying geometry. An important principle is the idea that one can associate numerical invariants to geometric objects, for instance via counting points or special curves, by topological and Hodge theoretic means, or via combinatorial and moduli theoretical approaches.

Students admitted to this RTG will study an exciting blend of geometry, algebra, and number theory, and use this to push the boundaries of mathematical knowledge in these fields through their own research.

Leading this RTG are Prof. Dr. Stefan Schreieder from LUH (speaker) and Prof. Dr. Gavril Farkas from HU Berlin (co-speaker). The remaining principal investigators are Prof. Dr. Gaëtan Borot (HU), Prof. Dr. Michael Cuntz (LUH), Prof. Dr. Ulrich Derenthal (LUH), Prof. Dr. Bruno Klingler (HU), Jun.-Prof.Dr. Thomas Krämer (HU), PD Dr. Angela Ortega (HU), Prof. Dr. Matthias Schütt (IAG), and Jun.-Prof. Dr. Isabel Stenger (IAG).
