Mathematics is the key to the future. Last week the @abel_prize was awarded in Oslo. Does math still matter? It does! A society that does not understand the algorithms shaping its information hands power to those who do. Thanks to @Klassekampen :

✨Wishing you a peaceful, bright and happy year 2026 ahead ✨

In case you always wanted to know why I think we are all mathematicians check out the video and hear me talk about my path to math at @UiTNorgesarktis and share advice to young mathematicians during this year's @abel_prize week.

Wonderful visit to our @eugloh19 - partner @UnivParisSaclay . Thank you very much for the invitation to @Institut_IHES - to look at joint interests with @liestoermer and for good discussions at the Math institute to explore collaboration in teaching math with @UiTNorgesarktis

The planar Evolute is a fascinating curve with a history going back at least to Apollonius (200 BC) and the (virtual) ink of its newest chapter is still fresh: "Return of the plane evolute".

We had the successful kick-off of our new Indo-Norwegian project: "Mathematical Theory of Data Transmission and Data Encryption" 🎉. Over the next 3 years, we’ll collaborate closely with our partners to foster educational and research exchanges between Norway and India. 🌍📊🔒

This year’s Mørketidens Mattemøte – the 7th edition – once again brought mathematicians from across Norway and the Nordic countries to @UiTNorgesarktis for two inspiring days of idea exchange and new connections. Thanks to Trond Mohn for the continued support for mathematics!

🌟 Do you know a PhD candidate nearing the finish line or a PostDoc looking for an exciting opportunity to pursue an ambitious MSCA Postdoctoral Fellowship?
@UiTNorgesarktis offers a fantastic program to help you prepare

Norway needs a boost for mathematics - also in fundamental research. Together with @UiT_DagRune, Hans Munthe-Kaas and Helge Holden we argue that the @liestoermer at @UiTNorgesarktis established together with @UiB is an important step in this endeavour!

A pleasant surprise to find this special issue of the Journal of Pure and Applied Algebra in the library of the Renyi Institut in Budapest 🙏

[Cordian Riener @Cordian1723]

The findings of the #TIMSS study are a wake-up call for Norway: a striking 42% of 5th graders and 66% of 9th graders report that they do not enjoy learning math. This is a serious problem – thanks to @Aftenposten for allowing us to comment on this

The 3rd edition of the Lie-Størmer Colloquium brings exciting mathematics to @UiTNorgesarktis - with financial support by @forskningsradet, the Trond Mohn Foundation and the Tromsø Research Foundation

What is academic freedom - especially with a perspective from Germany. Thanks to @Forskerforbundet ved @UiTNorgesarktis for a chance to discuss this.

Beautiful Northern Lights again this weekend 📸 Never can get enough of this!

[Cordian Riener @Cordian1723]

One of the privileges you get working at @UiTNorgesarktis : you get to see this dancing of the Aurora borealis quite frequently. BTW the study of this phenomenon motivated Car Størmer to switch towards computational mathematics- so it's underlying the @liestoermer center today.

[Cordian Riener @Cordian1723]

Beautiful #AuroraBorealis this weekend. I can never get enough of this

[Arctic Applied Algebra @ArcticAlgebra]

Congratulations to Arne and Robin 🎉

[Cordian Riener @Cordian1723]

Congratulations to Dr Arne Lien and Dr Robin Schabert who successfully defended their theses at @UiTNorgesarktis this week. Thanks to Tromsø Forsknings stiftelsen for the financial support of these PhD projects!

[Cordian Riener @Cordian1723]

Finally it's dark enough again to see the #Aurora dancing again over #Tromsø

[Cordian Riener @Cordian1723]

Interested to find out more about nonnegative and sums of squares symmetric functions of fixed degree? We study these objects with tools of tropical geometry - so very fitting for the summerly weather even in the Arctic at @UiTNorgesarktis

Ja, Norge har dessverre en matematikkrise – det er ikke bare Norge som står overfor denne utfordringen, men jeg synes at det er noen spesielle utfordringer her i landet.
Takk til @Klassekampen for å formidle dette og for å gi meg muligheten til å forklar.
