Swedish Network for Algebra and Geometry

Welcome to the 4th SNAG meeting!

Participants of the 2021 SNAG Workshop

We are happy to announce the 4th 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.


Joakim Arnlind (Linköping University)
Sergei Silvestrov (Mälardalen University)
Johan Öinert (Blekinge Institute of Technology)


The meeting will be held via Zoom on the 2nd and 3rd of December 2021.
