20/09/2020 | Workshop

Women in Mathematical Physics

The Women in Mathematical Physics Workshop at BIRS will have multiple research groups. One of them is on the topic of "Mathematical relativity: static Lorentzian length spaces" and fits into the framework of this SPP. It is led by Carla Cederbaum (Eberhard-Karls-Universität Tübingen, Germany) and Melanie Graf (University of Washington, US).

 

Applications for the workshop are open until Dec 20, 2019. For more information,

see sites.google.com/site/womathphys/.

Start: Sunday, 20/09/2020 09:00 am
End: Friday, 25/09/2020 04:00 pm

20/07/2020 | Conference

Geometric structures, compactifications and group actions

The unifying background of the meeting will be rigid differential-geometric structures, such as conformal and projective structures. This refers both to structures locally modelled on homogeneous spaces and to their curved analogues. One topic will be applications of Cartan connections to locally homogeneous structures, their moduli spaces, and compactifications. A related topic will be conformal compactifications such as Poincare-Einstein manifolds, and analogues for other ambient geometries. Another topic will be group actions preserving such structures and their rigidity.

Start: Monday, 20/07/2020 01:30 pm
End: Friday, 24/07/2020 12:00 pm
