In the early days of mathblogging, one was happy to get LaTeXRender working. Some years later, the majority of mathblogs were using the, more userfriendly, wplatex plugin to turn LaTeXcode into pngimages. Today, everyone uses MathJax which works with modern CSS and web fonts instead of equation images, so equations scale with surrounding text at…

Perhaps, the tips and tricks I did receive to turn a selection of wordpressposts into a proper ePubfile may be of use to others, so I will describe the procedure here in some detail. It makes a difference whether or not some of the posts contain TeX. This time, I’ll sketch the process for nonLaTeX… Read more »

There were some great comments by Peter before this post was taken offline. So, here they are, once again.

In preparing for next year’s ‘seminar noncommutative geometry’ I’ve converted about 30 posts to LaTeX, centering loosely around the topics students have asked me to cover : noncommutative geometry, the absolute point (aka the field with one element), and their relation to the Riemann hypothesis. The idea being to edit these posts thoroughly, add much… Read more »

Penrose tilings are aperiodic tilings of the plane, made from 2 sort of tiles : kites and darts. It is well known (see for example the standard textbook tilings and patterns section 10.5) that one can describe a Penrose tiling around a given point in the plane as an infinite sequence of 0’s and 1’s,… Read more »

In view or recents events & comments, some changes have been made or will be made shortly : categories : Sanitized the plethora of wordpresscategories to which posts belong. At the moment there are just 5 categories : ‘stories’ and ‘web’ (for all posts with low mathcontent) and three categories ‘level1’, ‘level2’ and ‘level3’, loosely… Read more »

One of the trends of 2010 was the proliferation of StackExchange sites. I guess by now most of us visit MathOverflow along with the arXiv daily. But, there are plenty of other StackExchange sites around that may be of interest to the mathematicscommunity : Mathematics somewhat less highbrow than MathO. Physics still in the betaphase… Read more »

As John Baez (and hopefully others) noticed most links here on NeB are now screwed up. For years I’ve used the Markdown syntax to include links in posts (that is something like [this is what you see](and here is the URL)). NeB used an older version ( Version 1.0.1k) of php Markdown to convert these… Read more »

Last year we managed to solve the first few riddles of the Bourbaki code, but several mysteries still remain. For example, who was the priest performing the BourbakiPetard wedding ceremony? The ‘faire part’ identifies him as ‘le P. Adique, de l’Ordre des Diophantiens’. As with many of these Bourbakijokes, this riddle too has several layers…. Read more »

To most mathematicians, a good LaTeXfrontend (such as TeXShop for Macusers) is the crucial tool to get the work done. We use it to draft ideas, write papers and courses, or even to take notes during lectures. However, after six years of blogging, my own LaTeXroutine became rusty. I rarely open a new texdocument, and… Read more »

Ever since I’ve upgraded to Snow Leopard I’ve been having problems with the webserver. At first there were the ‘obvious’ problems : mysqlconnection lost and phperror message. These were swiftly dealt with using the excellent Snow Leopard, Apache, PHP, MySQL and WordPress! advice from ‘tady’. Right now, access to this blog is extremely slow (and… Read more »

It all started with this comment on the noncommutative geometry blog by “gabriel” : Even though my understanding of noncommutative geometry is limited, there are some aspects that I am able to follow. I was wondering, since there are so few blogs here, why don’t you guys forge an alliance with neverending books, you blog… Read more »

Today, Alain Connes and Caterina Consani arXived their new paper Schemes over $ \mathbb{F}_1$ and zeta functions. It is a followup to their paper On the notion of geometry over $ \mathbb{F}_1$, which I’ve tried to explain in a series of posts starting here. As Javier noted already last week when they updated their first… Read more »

Last time I promised to come back explaining how to setup LaTeXsupport, figuring I had to tell you about a few modifications I had to make in order to get Latexrender run on my mac… A few google searches made it plain how out of touch I am on these matters (details below). But first,… Read more »

This hour we will install multiuser WordPress and turn it into a social network via BuddyPress

Set up your own WPMU+BuddyPress site on a spare Mac in no time.

Tim Gowers’ dream of massively collaborative mathematics got me thinking…

Terry Tao is reworking some of his better blogposts into a book, to be published by the AMS (here’s a preliminary version of the book “What’s New?”) After some thought, I decided not to transcribe all of my posts from last year (there are 93 of them!), but instead to restrict attention to those articles… Read more »

I’ve reinstalled the Google analytics plugin on december 22nd, so it is harvesting data for three weeks only. Still, it is an interesting tool to gain insight in the social networking aspect of mathblogging, something I’m still very bad at… Below the list of all blogs referring at least 10 times over this last three… Read more »

Over the last two weeks Ive ported all old neverendingbookspost from the last 4 years to a nearly readable format. Some tiny problems remain : a few TeXheavy old posts are still in $…$ format rather than LaTeXrendercompatible (but Ill fix this soon), a few links may turn out to be dead (still have to… Read more »

Take an affine $\mathbb{C} $algebra A (not necessarily commutative). We will assign to it a strange object called the tangentquiver $\vec{t}~A $, compute it in a few examples and later show how it connects with existing theory and how it can be used. This series of posts can be seen as the promised notes of… Read more »

It looks like I’m off the hook and can relax (after a few months of rewriting/correcting/learning LaTeXquirks). To all of you NeverEndingBooks readers : the bookproject has ended and will appear sometime this fall. It will be around 600 pages thick and cost just under 100$. This is about 4 times the amount NeverEndingBookers paid… Read more »

In 1877, Richard Dedekind discovered one of the most famous pictures in mathematics : the black&white tessellation of the upper halfplane in hyperbolic triangles. Recall that the group $SL_2(\mathbb{Z}) $ of all invertible 2×2 integer matrices with determinant $1$ acts on the upper halfplane via
