Linking to math reviews

Andrew Comech has written a tool called bibget. It does some neat things, e.g. UNIXPROMPT> bibget -r MR2121437 instantly retrieves the relevant math reviews reference in bibtex format. Colliand 00:07, 31 July 2006 (EDT)

Do we want to put references as [[Au2006a]] or [[Bibliography:Au2006a]]? Using the one page per reference section has the major advantage of allowing us to use the "what links here" link to hunt down all old links when a preprint is published, so I'm convinced this is the right way to go.

I think by fiat we are now using the former, as it is easier to type and looks nicer too. Presumably the Bibliography category will let us organise these pages easily even in the former case. Terry 23:59, 1 August 2006 (EDT)

I corresponded with AMS about linking to mathscinet from our bibliography pages. They directed me to the web page http://www.ams.org/msnhtml/getitem.html . So, for published papers in our bibliography we are free to link to mathscinet. For example, see http://tosio.math.toronto.edu/wiki/index.php/Bo1999b Colliand 12:31, 2 August 2006 (EDT)

Some reference pages, such as LiPo1993, have partial mathscinet links [1]. The string id at the end should be replaced by the associated math review number MR1249105. Is there an automated way to get these inserted into all the pages? Colliand 00:10, 3 August 2006 (EDT)

I am guessing that because we don't have specific tags for author, title, etc. one would need to build a reasonably smart system to automate things. Plus one expects references to continually be added by new authors, which we probably can't expect to adhere to any really complicated rules. Still a semi-automated system may be possible. Presumably once a mathscinet link is available one can query the AMS database in some automatic manner to aid our own somehow. Terry 00:39, 4 August 2006 (EDT)

Further correspondence with AMS from Drew Burton:

Getitem has the other nice feature that users without MathSciNet

licenses do get the cannonical bibliographic information and links to

the original article at the publisher's site when possible.

Another free tool that might be of interest is MRef for looking up

references in the MathSciNet database at http://www.ams.org/mref. It

takes normal reference strings and does an awfully good job of looking

them up in our database. It provides a variety of result formats.

E.g. I used it on your entry for BusPer1993 and got:

Buslaev, V. S.; Perel\cprime man, G. S. Scattering for the nonlinear

Schrödinger equation: states that are close to a soliton. (Russian)

Algebra i Analiz 4 (1992), no. 6, 63--102; translation in St.

Petersburg Math. J. 4 (1993), no. 6, 1111--1142 MR1199635 (94b:35256)

There is more information about our linking tools at

http://www.ams.org/tools in the "Linking" section.

It would be nice if we could write a link which takes the reference data on our bibliography pages already, uses that information to :search mathscinet, then displays the relevant mathscinet article listing. I don't know how to write such a link but will start to :experiment a bit. Colliand 11:19, 4 August 2006 (EDT)

In the long term, I think we should build a template for bibliography articles, with various arguments for bibliographic data such as author, title, etc. The advantage is that we can change the format of all articles simultaneously by editing the template. In the short term, the important thing is to get the basic data in the right place; data migration can then be done basically at any time.

There are no, non-trivial links to the old Bibliography page. Pblue 10:52, 10 August 2006 (EDT)

Categories

I've started putting in some categories into the Wiki; they provide a convenient way to dynamically index all pages associated to a single topic, and can themselves contain content of their own. Any page can have as many categories as it wants, so please feel free to design your own categories as you please. In the worst case they can always be merged or otherwise cleaned up. Terry 00:24, 29 July 2006 (EDT)

Redirects

Another useful Wiki feature is redirects. If a page contains nothing but the line

#REDIRECT [[some-other-page]]

then it will automatically redirect to some-other-page. This is useful for merging two otherwise redundant pages, or dealing with a concept that has many spellings or variant names, or with two topics which for some reason are being treated on a single page for now. Terry 00:24, 29 July 2006 (EDT)

Open for business?

The wiki is developing nicely. Not only is the conversion of the existing text reaching a point where the pages look nice (and invitingly easy to edit), the wiki format is also now suggesting some natural additions beyond the original brief of listing local and global wellposedness results for various equations. I particularly like the developing concepts category, making this wiki more encyclopediac (Dispersopedia, anyone?). Anyway, maybe we can start inviting some more people in on the project. Next week when I return to UCLA I think I will advertise it on my own web page. Terry 03:00, 31 July 2006 (EDT)

I have sent out a few invitations by email already. How about we arbitrarily declare Aug 7 "opening day"? :) Terry 00:39, 4 August 2006 (EDT)

Stubs

I have stolen the stub template from Wikipedia and adapted it here. A lot of smaller articles in need of expansion are now stubs to be expanded; see the stub category for a listing. It's easy enough to tag something as a stub, just put {{stub}} at the top of the offending page. Hopefully this will be one easy way for users to make significant contributions to this wiki :) Terry 01:07, 4 August 2006 (EDT)

Equation template

I'm trying to organise the standard information on each equation in a template, Template:Equation. You can see some instances of this template in action on the cubic NLS page, as well as on some of its children. I'll slowly start propagating this template across the equations (also an excuse to do some more cleanup as I revisit each page). Terry 01:18, 8 August 2006 (EDT)
