A finite and infinite-dimensional meeting on Lie groupoids, Poisson geometry and integrability

16-20 August 2021, Vienna

This workshop aims at discussing the interplay and the differences between the finite and the infinite-dimensional worlds in various topics in differential geometry. These include (as in the title) Lie groupoids and algebroids, Poisson geometry and integrability problems, as well as Riemannian geometry, representation theory, geometry of PDEs, etc.

There will be minicourses, invited and contributed talks. It will be a hybrid event: speakers and participants are encouraged to travel to Vienna, but there will also be the possibility for everybody to attend the workshop online.
