== Linking to math reviews ==

[http://www.math.tamu.edu/~comech Andrew Comech] has written a tool called [http://www.math.tamu.edu/~comech/tools/bibget/ bibget]. It does some neat things, e.g. UNIXPROMPT> bibget -r MR2121437
 
instantly retrieves the relevant math reviews reference in bibtex format. [[User:Colliand|Colliand]] 00:07, 31 July 2006 (EDT)
 
 
 
:Do we want to put references as <nowiki>[[Au2006a]]</nowiki> or <nowiki>[[Bibliography:Au2006a]]</nowiki>? 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. [[User:Pblue|Pblue]] 11:32, 31 July 2006 (EDT)
 
 
 
::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.  [[User:Tao|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 [[User:Colliand|Colliand]] 12:31, 2 August 2006 (EDT)
 
 
 
:Some reference pages, such as [[LiPo1993]], have partial mathscinet links [http://www.ams.org/mathscinet-getitem?mr=id]. 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? [[User:Colliand|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.  [[User:Tao|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. [[User:Colliand|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. [[User:Tao|Terry]] 15:04, 10 August 2006 (EDT)
 
 
 
:There are no, non-trivial links to the old [[Bibliography]] page. [[User:Pblue|Pblue]] 10:52, 10 August 2006 (EDT)
 
 
 
:There's a very basic [[template:bibliography]]. [[User:Pblue|Pblue]] 13:41, 10 August 2006 (EDT)
 
 
 
:: Looks good!  I tweaked it a little and set up one of my own references, [[Ta2004]], using the template as an example (though I don't have access to MathSciNet right now).  At some point we should migrate over but there is no urgency; it seems that one should search for a conversion process which is as automated as possible. [[User:Tao|Terry]] 15:04, 10 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). [[User:Tao|Terry]] 01:18, 8 August 2006 (EDT)
 
 
 
:More generally, we now have a [[DispersiveWiki:Template|template page]] to organise the emerging set of templates we will use.  Actually we could use some very short templates, such as a Schrodinger template to get that umlaut automatically in there, or perhaps templates for popular journals which contain HTML links to their web pages; the possibilities are endless :-).  [[User:Tao|Terry]] 15:05, 10 August 2006 (EDT)
 
 
 
 
 
== Copyright ==
 
 
 
Ugh, I hate legal issues, but at some point we have to choose a copyright license for this wiki to govern how the content can be copied
 
in the future.  It seems that most Wiki's use the [http://en.wikipedia.org/wiki/GFDL GFDL], which basically allows anyone to copy the material so long as they attribute the source, and also extend the same freedom to subsequent users of the material - the term for this seems to be "copyleft".  (See for instance [http://en.wikipedia.org/wiki/Wikipedia:Copyrights Wikipedia's copyright license].)  I am not experienced with these things but this seems reasonable enough to me.  Any thoughts?  (Eventually the licence sill need to be put on [[Project:Copyrights|this page]].)

I am actually gate crashing your site.  I have set up a wiki similar
 
to your own devoted to water waves.
 
[http://www.wikiwaves.org www.wikiwaves.org]
 
At the moment it is something of
 
a one man band - with help from a few arm twisted students and
 
collegues.  I am really impressed with what you have done here -
 
I naievely hoped that all I had to do was organise the website
 
and others would join.
 
I am wondering about a few points of connection
 
  
# It might be good to have links across wikis - i.e. if some water wave equations are dicussed on your site, then we should have a link to your site.
+
There is a [http://www.wikiindex.com/Category:Math list of Math Wiki's] on Wikipedia.  
#It might be useful to share resources - for example we have a program to convert latex to wiki. We have developed this program but it has also been developed by others and can always be improved
+
See for example the [http://en.wikipedia.org/wiki/Category:Partial_differential_equations collection] of PDE related pages on wikipedia. For basic concepts in PDE, perhaps we should further develop
#Marketing - it will be easier for me to say to collegues - checkout this great wiki on ... - why don't you help to make one for our subject.

those pages. For more specialized resources like a bibliography, it may be better to use this space. [[User:Colliand|Colliand]] 11:28, 15 September 2006 (EDT)
  
One idea I have is a central wiki site from which could contain
+
== Notation ==
general information and a pointer to scientific/mathematical wikis.
 
I also think that having a name for these kinds of wikis would
 
be useful - branding is everything!
 
  
I hope this posting was fine - I didn't know of a better place to put it.

This wiki looks like a great resource for people like me who don't deal with PDE's full time, but need help every once in a while.  One request: could someone compile a page discussing the notation?  As a physicist, I hardly ever see (for example) Δ used to denote the Laplacian; usually, it's ∇<sup>2</sup>.  Without a central notation page, it's hard to decipher some of the equations.  And does y<sub>x</sub> mean the partial derivative of y with respect to x?  Thanks.

Connections to other Wikis

There is a list of Math Wiki's on Wikipedia. See for example the collection of PDE related pages on wikipedia. For basic concepts in PDE, perhaps we should further develop those pages. For more specialized resources like a bibliography, it may be better to use this space. Colliand 11:28, 15 September 2006 (EDT)

Notation

This wiki looks like a great resource for people like me who don't deal with PDE's full time, but need help every once in a while. One request: could someone compile a page discussing the notation? As a physicist, I hardly ever see (for example) Δ used to denote the Laplacian; usually, it's ∇2. Without a central notation page, it's hard to decipher some of the equations. And does yx mean the partial derivative of y with respect to x? Thanks. JessRiedel 10:32, 18 February 2010 (UTC)
