Digesting the OpenAI preprints: Legibility, Correctness, and Insight

Posted in
Speaker: 
Multiple volunteers
Date: 
Fri, 16/10/2026 - 15:45 - 17:45
Location: 
MPIM Lecture Hall

Multiple volunteers read an OpenAI preprint and present their findings with regard to the following questions.

1) Is it true? (to the best of our judgment)
2) Is it well written and up to community standards?
3) Were papers appropriately cited?
4) Did OpenAI follow the advice of the advisory board?

After the volunteers present their experience and findings, we discuss questions. Ideally, we would come up with strategies to digest these papers or recommendations for OpenAI on how to improve the process.

MPIM
Date: 
Thu, 15/10/2026 - 15:00 - 16:00
Location: 
MPIM Lecture Hall
Parent event: 
MPI-Oberseminar

In this talk, we will discuss the history and construction of Khovanov homology and explore its connections to other areas of mathematics. Along the way, we will see how Khovanov homology brings together ideas from knot theory, topology, representation theory, and beyond, illustrating why it has become such a rich and influential subject.

Bézout's theorem for abelian varieties

I'll report on joint work with Olivier Debarre. The main result is that if A is an absolutely simple abelian variety over some field and X,Y are subvarieties of A, then the dimension of their sum X+Y equals the minimum of dim(A) and dim(X)+dim(Y). In characteristic 0, there is a very nice geometric proof, but that argument breaks down in characteristic p. Instead, we prove this result as a consequence of a theorem about perverse sheaves, building upon work of Krämer and Weissauer.
