The L-functions and modular forms database project

+John Cremona
(Submitted on 13 Nov 2015 (v1), last revised 28 Jan 2016 (this version, v2))
The Langlands Programme, formulated by Robert Langlands in the 1960s and since much developed and refined, is a web of interrelated theory and conjectures concerning many objects in number theory, their interconnections, and connections to other fields. At the heart of the Langlands Programme is the concept of an L-function.
The most famous L-function is the Riemann zeta-function, and as well as being ubiquitous in number theory itself, L-functions have applications in mathematical physics and cryptography. Two of the seven Clay Mathematics Million Dollar Millennium Problems, the Riemann Hypothesis and the Birch and Swinnerton-Dyer Conjecture, deal with their properties. Many different mathematical objects are connected in various ways to L-functions, but the study of those objects is highly specialized, and most mathematicians have only a vague idea of the objects outside their specialty and how everything is related. Helping mathematicians to understand these connections was the motivation for the L-functions and Modular Forms Database (LMFDB) project. Its mission is to chart the landscape of L-functions and modular forms in a systematic, comprehensive and concrete fashion. This involves developing their theory, creating and improving algorithms for computing and classifying them, and hence discovering new properties of these functions, and testing fundamental conjectures.
In the lecture I gave a very brief introduction to L-functions for non-experts, and explained and demonstrated how the large collection of data in the LMFDB is organized and displayed, showing the interrelations between linked objects, through our website www.lmfdb.org. I also showed how this has been created by a world-wide open source collaboration, which we hope may become a model for others.

I scored 11/11.
With interesting formations of English words and a large crop of loanwords, Indian English is a fascinating English dialect. Let's see how well you know it!

The following notes are a transcription and a translation into English of lecture notes (192 pages!) of de Bruijn's course on combinatorics, originally given in the 70s and 80s:

http://goo.gl/ZXO5AV

you may be surprised where they are hosted. From the introduction:

Combinatorics is mainly about counting. The nice thing about counting is that you learn something about the thing that you are counting. While counting, you notice that your knowledge about the subject is not sufficiently precise, and so counting becomes an educational activity. When two sets have the same number of elements, you try to understand why that is the case by establishing some natural bijection between the two.
N. G. de Bruijn recalls that sometime around 1975, he counted the number of a certain type of logics with three variables. There were a lot of them; some number with 14 digits. A little while later he saw an article that was about something completely different, but it concluded that the number of those objects was exactly that same number with 14 digits. He got curious and read the article very carefully. Indeed, if you thought deeply about it you could see that you could interpret those objects also as logics.

The global Langlands correspondence over function fields, after Vincent Lafforgue

Sophie Morel
(Princeton University)

February 20-22, 2016

Abstract: I would like to explain what the global Langlands correspondence over function fields is, to present Vincent Lafforgue’s results about it and to give an idea of his methods. In the most famous case, that of the general linear group GL_n, Vincent Lafforgue recovers the results of his brother Laurent Lafforgue (and, for n=2, of Drinfeld), but there are in my opinion a few advantages to his methods:
– Even in this case, they are totally new and technically simpler.
– They work for general reductive groups, for example symplectic groups or orthogonal groups.
– They have been inspiring new ideas to approach the local Langlands correponsdance over local fields of any characteristic.

Roses are red / Violets are blue / We’ve gone open access / So authors pay too!
Publishing an open-access paper in a journal can be prohibitively expensive. Some researchers are drumming up support for a movement to change that.

Can be expensive. Not necessarily is. Cf 'diamond' open access, and recent example Discrete Analysis, which would cost $10 per submission, but which is being covered by a grant.
