Next week I am delighted to be speaking at the workshop "LMFDB, Computation, and Number Theory" at @icerm.bsky.social , Brown University, USA. #LMFDB #ComputerAlgebra #AlgebraicGeometry #NumberTheory
LMFDB, Computation, and Number Theory (LuCaNT) 2025
This will be a one-week conference broadly focused on the topics of the LMFDB (http://lmfdb.org), mathematical databases, computation, and number theory. The conference will include invited talks, presentations by authors of papers submitted to the conference and selected by the scientific committee following peer-review, as well as time for research and collaboration. We plan to publish a proceedings volume that will include all of the accepted papers. The field of mathematical databases has emerged as an important area of research at the intersection of computer science and mathematics. It seeks to address questions that arise when organizing, storing, and providing access to mathematical knowledge in a structured manner. These databases are intended to be easily searchable and navigable, providing researchers, educators, and students with a convenient way to access mathematical content. There are many challenges in developing and maintaining mathematical databases, ranging from data quality and integration, to standardization, search design, updating and maintenance, and usability. In addition, many algorithmic and theoretical questions emerge naturally when considering systematic computations that must be done on a large scale.

oh yay! my group is hoping to sneak in to some of the talks since we're doing LMFDB-related work. hopefully we'll run into each other!

Very true, but I've actually learned quite a bit about the structure of subgroups in the process of making the lattices. I can't quite articulate what, but it's definitely been insightful.

In fact, this is a *great* exercise to do! From my class.

Yes, it does! It is somewhat limited to only a few smallish group (I think I have most in my book somewhere). I'll email Sam Schiavone and David Roe from LMFDB; at the JMM they asked me if I had suggestions for it (other than OD_n --> SA_n, and adding the diquaternions DQ_n), this is a great one!

First, let me just express my excitement of seeing the term "subgroup diagram" in the wild! 😀 I'm really hoping it catches on!

Subgroup diagram: basically a subgroup lattice with the conjugacy classes collapsed into single nodes, w/ left subscripts denoting their size (à la LMFDB & GroupNames).
February 18, 2025 at 1:39 AM
With a few exceptions, LMFDB is basically an improved version of GroupNames w/ lots of extra features. They even got help from GroupNames founder Tim Dokchitser in getting it off the ground. They use the same conventions for subgroup diagrams (=lattices collapsed by conjugacy classes).

Is there a way to make LMFDB show you subgroup *lattices* rather than subgroup *diagrams*? beta.lmfdb.org/Groups/Abstr...

Recently I became an associate editor of the LMFDB, so I am a very small part of the large team behind that database (which is awesome and you should explore it!). I will also be an assoc editor of LuCaNT 2025:

The elliptic curve with LMFDB label 49.a2 hopes you have a nice Friday and a great weekend.

This sounds a lot like what the LMFDB dreams of doing for modular forms.

I computed two of these, just to observe that they're different, and in lieu of, say, automated production of these from lmfdb data.
February 16, 2024 at 3:13 AM
which one is this? could you link to the lmfdb page for it?
