Autumn School From T-duality via K-theory to Representation Theory

We are glad to announce the upcoming Autumn School "From T-duality via

K-theory to Representation Theory" taking place in Göttingen, September

30th - October 4th.

The aim of the Autumn School is to bring together young researchers with

experts in the research areas of T-duality, K-theory, representation theory

and their interplay. The school consists of four mini-courses leading

towards a broad understanding of the topic from different perspectives.

Mini-Courses speakers:

- Francesca Arici (Leiden)

*C*-algebras and (K)K-theory in solid-state physics*

*- *Marco Gualtieri (Toronto)

*Groupoids, Gerbes and Generalized Kähler geometry*

*- *Nigel Higson (Penn State)

*C*-algebra K-theory and Tempered Representation theory*

- Konrad Waldorf (Greifswald)

*The higher geometry of T-duality*

Please find more information in the website of the School:

www.uni-goettingen.de/en/683710.html

Financial support is available for a limited number of young participants.

The deadline for requesting financial support is the July 15th.

We hope seeing many of you in Göttingen!

Spring School „Modern Aspects of Analysis on Lie Groups“

In this Spring School, we are seeking to bring together early and advanced doctoral students as well as postdocs with experts in the analysis on nilpotent Lie groups. The theme of this Spring School is Modern Aspects of Analysis on Lie Groups. In particular, the (proposed) topics of the advanced courses of the spring school are: Calculus on nilpotent Lie Groups, Weyl calculus on graded Lie groups, Fourier restriction on Lie Groups/sub-Riemannian Geometry, Wavelet aspects on Carnot-Groups. The Spring School is organized by the research group Analysis of PDEs under the umbrella of the DFG funded Research Training Group RTG 2491 Fourier Analysis and Spectral Theory.

This spring school is a follow-up to the Summer School Singular Integrals on Nilpotent Lie Groups and Related Topics which took place September 2022.

Topological and Homological Methods in Group Theory 2024

This is the fourth instalment of the THGT conference series. As its predecessors, the conference takes place in Bielefeld in spring, and as before it welcomes researchers studying groups through their interactions with topology and homology, as well as people interested in entering the subject.

Riemannian Topology Meeting

The Riemannian Topology Meeting is an irregularly recurring activity addressing mathematicians interested in the interplay of algebraic and geometric topology with riemannian geometry. Its tradition reaches back to 2012 during which it took place at the universites of Fribourg, Karlsruhe and Göttingen. This years meeting takes place on the 9th and 10th November, in Fribourg.

Autumn School on Large Scale Geometry

Large scale geometry (a.k.a. coarse geometry) is the paradigm of studying metric spaces from "far away'', neglecting all the local information and just focusing on features of the space at infinity. The aim of this school is to introduce terminology and techniques from large scale geometry and to show how they can be used in a variety of contexts. These include (but are not limited to) geometric group theory, index theory, operator algebras, (geometric) topology.

The school will feature four minicourses by leading experts in the field, each of them consisting of four 50-minutes lectures plus one exercise/discussion session. The minicourses will be aimed at a broad audience.

Young participants are also encouraged to present their research with a short talk in a "gong-talk" session.

A workshop on Einstein manifolds

The Einstein condition is viewed by many as the "most interesting" notion of constant curvature, since there are not too many and not too few examples of Einstein manifolds. In the 1980s the brightest minds of the field rallied once more under the banner of the Besse group, as they had before. This time the result was an epochal work on the topic of Einstein manifolds. Still, there were many open questions left.

Time has passed, and more progress has been made. So let us not dwell on the past, but stride forward into the Crazy World of Arthur L. Besse!

Buildings 2023

The Buildings conference series has a long tradition starting in Würzburg in 1994 and this will be the 29th installment. The topic is not restricted to buildings and their applications but talks from neighboring areas such as representation theory, geometric group theory, and algebraic groups are welcome and have been common

in the past.
