## New reference manager colwiz looks great for mathematics

Posted by Andreas Holmstrom on July 11, 2013

Over the years I have tried out (and discarded) a number of reference managers, including Papers for Mac, Mendeley, Bibdesk, and Zotero. Very recently, thanks to a tip by Magnus Carlsson, I finally found one which actually seems to be doing what I want it to do: Colwiz. Here are some of the reasons I like it:

- Articles are stored in the cloud AND on my own computer. I really want both.

- Everything just works, even if you’re not a super-hacker like Andrew Stacey.

- I can easily import (lots of) references from MathSciNet (still not possible in Mendeley, which is why I once posted my angriest online comment ever on their feedback page). For example, I just imported references to all articles ever written by Gillet and/or Soulé in less than a minute.

- Colwiz automatically includes links (via doi and also via MathSciNet) to online versions of the article. I think this is brilliant.

- The desktop application apparently does not automatically mess up my own folders and naming of files.

- It’s free (at least as long as you don’t want more than 2 or 3 GB of pdf articles in the cloud).

- They have apps for iPhone, iPad, and Android.

- It’s designed for collaboration.

So far I haven’t discovered any major drawbacks. I doubt that their e-reader handles djvu files, and it seems (unless I’ve missed it) that you search in your own references on general keywords only, without the option to use fields like journal name, time interval etc.

Finally, some links to related things: A MathOverflow question on tools for organizing papers. Wikipedia’s rather complete list of reference managers. Konrad Voelkel’s blog, where he has written on managing papers, managing metadata, and much more.

## Iwasawa theory resources

Posted by Andreas Holmstrom on July 9, 2013

Iwasawa theory is a branch of number theory with important applications to class groups of number fields and to conjectures on special values of zeta functions. Here are some starting points for learning more about this.

(You might find other references at Wikipedia and in this general MathOverflow question.)

**Book references:**

- Lang: Cyclotomic fields I and II (Google Books)
- Washington: Introduction to cyclotomic fields (Google Books)
- Neukirch, Schmidt, Wingberg: Cohomology of number fields (Google Books)
- Coates and Sujatha: Cyclotomic fields and zeta values
- Iwasawa Collected Papers (2 volumes)
- Noncommutative Iwasawa Main Conjecture over Totally Real Fields (SpringerLink)

**Surveys and introductions online:**

Manfred Kolster: K-theory and arithmetic (Very nice basic introduction to zeta values and Iwasawa theory)

Introductory notes by Jim L. Brown

Surveys of Sujatha:

- The Main Conjecture (with Coates)
- On the mu-invariant

Surveys of Venjakob:

- From the BSD over the ETNC to noncommutative Iwasawa theory
- From classical to noncommutative Iwasawa theory

A survey of Greenberg. Other surveys, and a book draft, on Greenberg’s webpage.

Matthias Flach surveys:

A survey by Mitchell from the Handbook of K-theory, on Iwasawa theory and homotopy theory. (See also an interesting blog post of Eric Peterson here, for some possible connections with chromatic homotopy theory)

For noncommutative Iwasawa theory, here are some additional key papers:

- Fukaya and Kato: A formulation of conjectures on p-adic zeta functions in noncommutative Iwasawa theory
- The five-author paper
- Kakde: The main conjecture of Iwasawa theory for totally real fields from arXiv Front: math.KT by Mahesh Kakde. Some of this is reviewed in arxiv preprints by Venjakob and/or Schneider.
- Skinner and Urban: The Iwasawa main conjecture for GL2
- Various papers of David Burns
- The Bertolini-Darmon paper in Annals
- Malte Witte: Noncommutative Main Conjecture of Geometric Iwasawa Theory

Finally, a list of all papers on MathSciNet labelled with subject code 11R23 (Iwasawa theory), the latest papers on arXiv, and a MathOverflow search on “Iwasawa”.

## Free access to all Elsevier material for postdocs between jobs

Posted by Andreas Holmstrom on July 8, 2013

If you are a postdoctoral researcher between jobs, you can apply for free access to all Elsevier/ScienceDirect scholarly articles here. It seems like all you need is a letter on official letterhead from your last institution, and what you (might?) get is free access for a 6-month period, with a personal access code. Note that you have to apply before Aug 31st! Probably this is something they’re experimenting with partly in response to criticism and boycott, but regardless of your opinion on Elsevier and the boycott debate, access to “their” articles might be useful.

## Grothendieck anagram

Posted by Andreas Holmstrom on January 6, 2013

Looking back on the mathematical year 2012, the most exciting thing happening was probably Mochizuki‘s work on the abc conjecture. Something I had hoped to see during 2012, was the writings of Grothendieck, restored to the Grothendieck circle website. Sadly, this has not happened, as Grothendieck himself apparently is opposed to it. However, it is not clear (to an outsider) if he is opposed to having a website dedicated to his memory and/or publishers making money out of his writings, or if he is actually opposed to his hardcore algebraic geometry texts being made available for free to interested mathematicians. Looking carefully at the name Alexander Grothendieck, one observes that permuting the letters yields the sentence “Hardcore EGA, extend link!”. Although not a decisive argument in the moral/legal debate over Grothendieck’s letter, perhaps it means something ;-)

One a similar note, the sentence “hi’ risk abstract banana hack” is an anagram of “Banach-Tarski”, while “Plain Anarchy Got Us! Shriek! Ahhh!!” is an anagram of “Hartshorne playing shakuhachi”.

Finally, a little anagram puzzle for those of you who need a small recreational break (can also be used as homework for students you for some reason do not like). Let n be a positive integer, and let S be the set of integers between zero and n (inclusive). Let N be the number of anagrams expressing valid arithmetic equalities between elements in the set S. Example: Twelve plus one = eleven plus two. Try to compute N for small values of n. Do you see a pattern? How does N grow with n? What happens if you replace the word “integer” with the word “rational number with bounded height”?

Happy New Year 2013!

## Postdoc opportunities in France

Posted by Andreas Holmstrom on January 25, 2011

I found my current job in Bordeaux thanks to this blog post of Minhyong Kim, and will now try to make someone else a similar favour.

Firstly, there are postdoc positions at INRIA advertised here. The subject area is computer science and applied mathematics, but I know that in the past this has included computational arithmetic geometry. If anyone is interested, I can put you in touch with someone at the maths department here in Bordeaux who has hired math postdocs via INRIA before (am hesitant to post his name and email address here without his permission). Just leave a comment or send me an email.

Secondly, there is some European Union money for a number of postdoc positions in the Aquitaine region. As far as I understand, the first step towards an application is to contact a potential host researcher, for example at the IMB.
