This is a wiki-lab for collaborative work on Mathematics, Physics and Philosophy — especially from the n-point of view: insofar as these subjects are usefully treated with tools and notions of category theory or higher category theory.
We think of this wiki as our lab book that we happen to keep open for all to see.
The purpose of the Lab is to provide a public place where people can make notes about stuff. The purpose is not to make polished expositions of material; that is a happy by-product.
We all make notes as we read papers, read books and doodle on pads of paper. The Lab is somewhere to put all those notes, and, incidentally, to make them available to others. Others might read them and add or polish them. But even if they don’t, it is still easier to link from them to other notes that you’ve made.
For more see About.
We originally designed this place as as an adjunct to the -Category Café, but it's more independent now.
While we work on the Lab, we talk to each other on the nForum. We inform ourselves about latest edits to the Lab in the part nForum – latest changes. Have a look around there.
If after looking around for a while you feel like contributing yourself, you are welcome to do so. But read About to be sure you understand what we are doing here (to the extent that we understand this ourselves, at least). Then see the HowTo-page for more details.
The Lab displays mathematical symbols using MathML.
Notice that you don’t need to know any MathML. Only your browser does. You write formulas into the Lab between dollar signs in iTeX, which is designed to be very similar to ordinary LaTeX.
Some web-browsers, notably Firefox, know how to display MathML automatically, although you may need to install some fonts. For InternetExplorer one needs the MathPlayer plugin; download is quick and easy and free. For more see HowTo.
The Lab is a community undertaking. But for all matters that do require that the Lab is represented to the outside by an official decision-taking body, we have the steering committee. Nobody “is in charge of the Lab”. But the steering committee is the closest approximation to a body being in charge that we have.
