Swedish Network for Algebra and Geometry

Welcome to the 6th SNAG meeting!

21st - 22nd of March 2024

Participants of the 6th SNAG Workshop

We are happy to announce the 6th 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 take place at Linköping University from Thursday 21st of March to Friday 22nd of March 2024. Participants are encouraged to arrive on Wednesday 20th of March since the talks start on Thursday morning. Please note that participants are expected to make their own arrangements for travel and accommodation. Clarion Hotel Slottsparken and Best Western And Hotel are two hotels that are located in the city center with a convenient and quick bus connection to the university.

From "Linköping Resecentrum" you can take bus 12 (to "Universitetet") or bus 4 (to "Nobeltorget") to get to the university. If you are staying at Hotel Clarion Slottsparken or Best Western And Hotel, you may take bus 12 from "Länsstyrelsen" to "Universitetet".


If you would like to participate, please send an email to Joakim Arnlind.


The lectures will be held in lecture room "Planck" (see map).
