What do they mean and what purpose do they serve?

They're tags that are used on MathOverflow. The reason they were adopted there is that professional mathematicians are already familiar with the two letter arXiv codes for various areas of mathematics.

I don't think it makes sense to have these tags on math.SE. That is, I think [pr.probability] should just be changed to [probability]. A moderator can do this easily, so there's no need to go on a retagging spree.

    $\begingroup$ Ah. I've never even heard of arXiv before. It seems redundant - the textual tags are more accessible and less confusing. Especially for people like me, who are interested in mathematics (it's considered a supporting discipline for my field) but aren't and probably will never be experts. $\endgroup$ – Thomas Owens Jul 26 '10 at 1:28

    $\begingroup$ Would you take a look at Larry Wang's comment on this thread and give us a heads up over here about what we can expect for TeX support? $\endgroup$ – Tom Stephens Jul 26 '10 at 1:30

    $\begingroup$ @Thomas: I completely agree. Since the target audience of math.SE isn't familiar with the arXiv, the two letter codes are just confusing. @Tom: done and done. $\endgroup$ – Anton Geraschenko Jul 26 '10 at 2:41

This is a carry over from Math Overflow.

However, it seems as though it is an impossible-to-enforce convention here.

    $\begingroup$ impossible-to-enforce convention: because relatively few people think it is worthwhile, or even well-specified for this site. $\endgroup$ – Charles Stewart Jul 26 '10 at 1:21
