Swedish Network for Algebra and Geometry

Welcome to the 3rd SNAG meeting!

Participants of the 2020 SNAG Workshop

We are happy to announce the third meeting of the Swedish Network for Algebra and Geometry. The purpose of the network is to develop the interaction between mathematicians working in the fields of algebra and geometry at Swedish universities. In particular, we envisage an active participation of PhD students and young researchers with the aim to build networks and encourage collaboration.

Organizers: Joakim Arnlind, Sergei Silvestrov and Johan Öinert.


The meeting will be held via Zoom on the 24th and 25th of September 2020.
