<![CDATA[Hello world!]]>Hello world! I'm a mathematician based at Technical University Berlin interested in the intersections of algebra, analysis, probability and geometry. Most precisely, I'm studying iterated-integrals signatures of paths and related constructions from both an algebro-geometric and noncommutative/nonassociative algebra angle.

I'm very closely following the critical discourse around LLMs/GPT and mathematics. This was one of my main motivations for setting up this account. However, I'd like to use this account more generally for scientific communication, within mathematics and beyond. I hope to share more about my current research soon!

Meanwhile, have a look at my website if you'd like: https://www.rosapreiss.net/

Since my account is brand new and I'm looking for new contacts, feel very free to comment if you'd like to connect, and boosts are appreciated of course 🙂

Hello! I think there is a pack of Academic Accounts somewhere, but I don't know where.

i enjoy mostly not getting your thing (definition of path?), but that is perfect here. Just scream your most special awesome stuff into the void until it reacts. Look who reacted to find possible contacts.
It is way slower here and you only see what happens at the moment, so the time you post decides who sees the post (except your followers). If you post pictures, please provide alt text focusing on what you want to tell for the many visual impaired around here.

Welcome! I hope you will find stimulation and fun here.

I'm a retired engineering prof, by no means a mathematician. I appreciate that you linked your website, and gave a publication list. Interesting! I feel my brain expanding a tiny bit by only reading the titles. Will read more.

Horribly, a lot of my reading and thinking these days is on politics, history, and the fragility of democracy. So my posts won't interest you much, probably, but I look forward to seeing yours.

A favourite subject of mine, where wonderful terms and concepts such as 'punctuated equilibrium' pepper the landscape.

I have trouble with basic addition, subtraction, division and multiplication, so naturally I went into construction and ended up as a technician for agricultural engineering projects. It's fine. I also get to draw lots of pretty pictures on maps. I'm also following the LLM/diffusion model news closely because ofy interest in climate change.
