This blog is now midway through its silent transition mode (in which the author is very busy, and will probably en up somewhere interesting, but cold and very cloudy).
Some items spotted recently:
Vincent Lafforgue, a younger brother of Fields Medalist Laurent Lafforgue, has apparently proved a substantial part of the original Langlands conjectures, encompassing some of his brother’s results! This has been the subject of three lectures at IHÉS, and Gaitsgory has talked about it at Harvard. Vincent Lafforgue was already famous for his work on the Baum-Connes conjecture (the things he did more than a decade ago had earned him an EMS prize in 2000 — see this Bourbaki seminar — and more recently a second Bourbaki seminar was devoted to some of his new work on that topic).
The prize season is in full swing, but it’s still difficult to predict who will win a Fields medal next summer (some of the names in my earlier list have come up recently, but with other names too) :
The AMS has announced that their two Gold Open Access journals have started accepting papers on september 1, 2013: the Proc.AMS(series B) and Trans.AMS(series B) journals.
So, since they already had Green Open Access for all their previous journals, I’m really curious to see how it pans out.
The APC for a paper in Proc.AMS(B) are $750 per paper in 2014, and $1500 after that. For Trans.AMS(B) it is $1,400 at discount rate, and then $2,750 from 2015 onwards.
As I understand it, the differences are:
Electronic version available to
subscribers only. But two important tweaks: (a) archives of issues older than 6 years are free to all, (b) final preprint versions posted on the arXiv or personal homepage are allowed (so just page or theorem numbers might differ in the published version).
available to all on the journal website permanently under CC licence
costs to readers’ university
Proc.AMS (electronic only) costs $1,083 per year to institutional members (2014 rate)
costs to authors’ university
Each Proc.AMS(B) paper costs $750 (2014 rate with 50% discount)
publication delay after acceptance
about 1 year and 2 months (13 issues of backlog as of august 31)
So basically, on purely economic terms, Green beats Gold straightforwardly.
But maybe a PhD student or postdoc who prefers to have on a CV a final publication reference rather than something ‘to appear in’ may want to go for Gold. That’s about the only reason I can think of. What remains to be seen is whether or not this would start a vicious cycle of some sort (not sure what, if any).
Edit: come to think of it, the vicious cycle might be “so you see, people want to publish this way, so we’ve decided to phase out paper journals and green OA entirely”.
Or is it extraordinaly (pun intended)? You have to wonder!
Indeed, his latest one posted to the arXiv has, among the frontpage footnotes, “Publication 1023″! There is (at least) that amount on his archive (although the 1000th is marked as ‘SAVED’, presumably for something especially noteworthy), and 630 of them are on the arXiv (as of today…).
He apparently is 68, and received his PhD in 1969 (the year he started publishing), so that’s 1023/(2013-1969)=23.25 papers per year, for 44 years! For comparison, other prolific recent mathematicians include Erdős (about 1525 papers in about 67 years) and Tao (about 250 papers and 17 books in 17 years, according to wikipedia; so just for papers he is on track for 1000 in about 68 years).
Back to Shelah, and it seems that many of his papers are moreover important, with one in JAMS just in the past couple years, while his older works have been recognised many times, including by the 2013 ‘Seminal Contribution to Research’ Leroy P. Steele prize. Slightly more information on his work pre-XXIth century is on the MacTutor, but a self-contained text (at the level of a graduate student or non-specialist mathematician) giving a moderately technical overview of his main achivements would be very welcome, I’d imagine (the slides for his Plenary Talk at the 2012 ECM are interesting, for instance).
Truly exciting advances in DNA-based information storage are being made, resulting in something that is robust, lasts thousands of years and has very high density compared to flash memory. And they announce “commercially viable technology within five years”!
Hopefully, some self-generating “archive of human knowledge” will one day be designed: a DNA fragment that, when put into some appropriate medium (e.g. your basement lab, or even an ocean on some distant planet that harbours reasonable chemistry), starts producing a biomachine that is a kind of tablet computer (with touchscreen and sound), and said biomachine will then be used to read the data contained on the rest of that DNA fragment (where the actual archive of human knowledge has been encoded).
Then put that at several locations across the solar system and beyond, for good measure.
To test the Poll tool, here are a few semi-serious questions and answers.
Normally, things are set up to hide results and block repeat voters with both cookies and IP filtering. I’ll probably reveal the results in a month time when the polls close.
In both poll you should be able to pick several answers, if so inclined.
Here’s the first one:
And here’s the second one:
Update (august 27, 2013): I’ve now closed the polls, and it’s clear this corner of the web is not really visited at all, especially in august. Indeed, there’s been only 4 votes on each poll, and each one for a different answer. Thanks to those who voted, but no statistically significant result can be drawn from them, which ends this little experiment.
Since the list of mathematics open access journals over at the Directory of Open Access Journals is both incomplete and full of obscure journals, here is my subjective list of serious ones. Feel free to mention omissions (although I reserve myself the choice of possibly not adding them).
[Edit: in fact, I am mostly interested in serious ones which moreover do not charge any submission fees (so-called 'article processing charges' APC). So, only those will be listed (I'll make an exception for some journals that have APC with a generous fee-waiver policy).]
