[This is a guest post by Boris Alexeev. Now over to Boris.] I’m here to tell you about various exciting developments centering on Erdős problems, especially involving the formalization of old and n…

So it’s an interesting time for computers-doing-mathematics. A couple of interesting things happened in the last few days, which have inspired me to write about the question more broadly. Fir…

A project to map out the relations between different equational theories of Magmas. - teorth/equational_theories

We construct the Lie algebra of a Lie group, where the bracket is given by the vector field bracket of invariant vector fields associated to an element of the Lie algebra, i.e., the tangent space a...

Recent math benchmarks for large language models (LLMs) such as MathArena indicate that state-of-the-art reasoning models achieve impressive performance on mathematical competitions like AIME, with th...

A project to digitalise results from physics into Lean. - HEPLean/PhysLean

Class Field Theory in its cohomological form is one of the highlights of early 20th century mathematics, and is now understood as the abelian case of the Langlands Philosophy. Although it sounds like ...

A month or two ago I wrote this post which expressed my frustration with various issues around private datasets as a way of measuring the mathematical abilities of language models. More generally I was frustrated about the difficulty of being able to judge closed source software owned by a tech company when it's extremely difficult to do science (i.e. perform reproducible experiments) on it.
