An arbitrary collection (only sporadically updated) of things I have written or talked about throughout the years.
WARNING: Often when I write maths, it is for my own sake, and sometimes “just on vibes”. So therefore, notes from writeups or from talks I’ve held WILL contain a lot of erros!

Other talks
I have also held a number of different non-mathematical talks, but I do not have a complete list. The list of the coolest talks the last years would include motivational talks about studying mathematics at my local high school in 2019, hosting webinars on studying mathematics for high schoolers in 2020 and giving an “experience based” course on how to study mathematics at the 2021 entry week for new students.
These include mathematical talks given to a non-mathematical audience, such as:
- A talk on “approaching algebraic topology” given for Fagerlia/Ålesund Vgs in 2023.
- A talk on topological data analysis given at PwC Oslo in 2023.

$\Delta t$ articles
$\Delta t$ is the newspaper of the student association Delta, which is the association for students in mathematics and/or physics at NTNU. We mostly write in quite unformal articles in Norwegian, and hence most of the articles below are in Norwegian.
