Past events and news of the Graduiertenkolleg 1821 in Freiburg

- Summer School "Special Holonomy – Geometry and Physics", September 23 – 27, 2019, Freiburg (HS II, SR 404, 403, from Sep 23, 2019 09:00 AM to Sep 27, 2019 04:00 PM)
- Sommer School "o-Minimal Structures in Algebraic Geometry", September 9-13, 2019 Freiburg (HS II, SR 404, 403, 125, from Sep 09, 2019 09:00 AM to Sep 13, 2019 04:00 PM)
- Originating in model theory, o-minimality is a tameness property of real sets which enjoys important finiteness properties. O-minimal structures have recently found a number of important applications to algebraic and arithmetic geometry. The aim of this summer school is to provide an introduction to these ideas for an audience of non-experts.
- Darmstadt-Erlangen-Freiburg Seminar on Conformal Field theory, Friday, July 5, 2019 Institut für Mathematik Albert-Ludwigs-Universität Freiburg (room 404 of the Mathematics Institute (Ernst-Zermelo-Strasse 1, fourth floor), from Jul 05, 2019 02:00 PM to Jul 05, 2019 06:00 PM)
- Lecture Series "Hypoelliptic laplacian and applications", 20-24 May 2019, Universität Freiburg (SR 414, Ernst-Zermelo Str.1, from May 20, 2019 09:30 AM to May 24, 2019 12:00 AM)
- The purpose of the lectures is to give an introduction to the hypoelliptic Laplacian and to the results which have been obtained so far by this method. The hypoelliptic Laplacian gives a universal interpolation between the Laplacian and the generator of the geodesic flow through a family of hypoelliptic operators acting on a bigger space than the original Laplacian. There are as many hypoelliptic Laplacians as there are Laplacians. To this deformation of operators corresponds an interpolation of dynamics, that interpolates between Brownian motion, with the most irregular paths possible, and the geodesics which have the most regular trajectories. Explicit geometric formulas for certain orbital integrals will appear as consequences. These give in arbitrary dimensions the analogues of the geometric formula obtained by Selberg in the case of Riemann surfaces. The lectures are given by Jean-Michel Bismut. Additionally, he will give a Colloquium talk for the general audience.
- Fourth Meeting for Young Women in Mathematics “Cohomological Methods in Geometry” (Room 404, Ernst-Zermelo Str.1, from May 01, 2019 05:00 PM to May 03, 2019 03:00 PM)
- We are hosting a meeting for young women in mathematics at the University of Freiburg as part of our program "Cohomological Methods in Geometry".

- The aim of the meeting is to bring together mathematicians working on Quantum Field Theory from different perspectives through the talks by some of the most known and active international researchers. This event represents an important occasion to review recent achievements and to start fruitful discussions on the open issues and on the directions of future research.
