MathSciNet Demos at AMS Sectional Meetings

Editors from Mathematical Reviews will be at two upcoming AMS Sectional Meetings to give demos of MathSciNet, as well as to answer questions. This is a great chance to learn more about using MathSciNet, about updating your author profile, about reviewing, or about Mathematical Reviews in general. Continue reading

Metadata

MathSciNet is full of metadata.  We create our own metadata.  We receive metadata from many of the publishers of the journals we cover.  So what are metadata?  (Or what is metadata?)  The simplest explanation of metadata is that they are a type of data that describes other data.  The classical example is the metadata found in card catalogs from libraries.

A card from a card catalog, with annottions

 

Lots of information is on the card.  Note that before the annotation, nothing is labeled. There are accepted rules that tell a librarian (or a patron) what each piece of data is.  For most pieces of this data, a non-librarian would be likely to figure out what everything meant. Continue reading

An exceptional review about inner model theory

Today I’m making two blog posts about exceptional reviews: one review of a book and one of a paper.  This post is about Grigor Sargsyan‘s exceptional review of a paper:  John Steel‘s chapter, An outline of inner model theory, in the Handbook of Set Theory edited by Matthew Foreman and Akihiro Kanamori [MR2768678].  The other post is about Harald Helfgott‘s review of Terry Tao‘s book Expansion in finite simple groups of Lie typeContinue reading

An exceptional review about expansion in groups

Today I’m making two blog posts about exceptional reviews: one review of a book and one of a paper. This post is about Harald Helfgott‘s review of Terry Tao‘s book, Expansion in finite simple groups of Lie type, published by the AMS. The other post is about Grigor Sargsyan‘s exceptional review of a paper:  John Steel‘s chapter, An outline of inner model theory, in the Handbook of Set Theory edited by Matthew Foreman and Akihiro Kanamori [MR2768678].

Jonathan Borwein

Jonathan Borwein passed away on August 1st.  He was a prolific mathematician, with 427 publications as of this writing.  He was also quite broad, publishing in number theory, operations research, calculus of variations, and many other subjects.  Many people knew him for his book with his brother PeterPi and the AGM.  His most cited work in MathSciNet is his paper “On projection algorithms for solving convex feasibility problems” with Heinz Bauschke (the review is reproduced below).  Borwein was also known for promoting experimental mathematics, and was the founding director of the Centre for Experimental and Constructive Mathematics at Simon Fraser University.  But many people knew Borwein’s mathematics directly as a mentor or as a collaborator.  He had many graduate students and 163 collaborators on published papers.   Continue reading

MSC2020 – Mathematics Subject Classification update

MSC2020

Announcement of the plan to revise the Mathematics Subject Classification

Mathematical Reviews (MR) and zbMATH cooperate in maintaining the Mathematics Subject Classification (MSC), which is used by these reviewing services, publishers, and others to categorize items in the mathematical sciences literature. The current version, MSC2010, consists of 63 areas classified with two digits refined into over 5000 three- and five-digit classifications. Details of MSC2010 can be found at www.msc2010.org or www.ams.org/msc/msc2010.html and zbmath.org/classification/.

MSC2010 was a revision of the 2000 subject classification scheme developed through the collaborative efforts of the editors of zbMATH and MR with considerable input from the community. zbMATH and MR have initiated the process of revising MSC2010 with an expectation that the revision will be used beginning in 2020.

An exceptional review of a paper by Bhatt and Scholze on étale topology

Another great review.  Here Pieter Belmans reviews a paper by Bhatt and Scholze on étale topology.  Before describing the authors’ work, Belmans tells us where étale topology comes from and why some news ideas might be necessary.  He then gives a quick description of what Bhatt and Scholze are doing and why it is a good thing.  Once the history and context are in place, Belmans goes through the contents of the paper, with plenty of comments to help the reader.  He concludes by giving a reference to the Stacks Project, where you can find out lots more about pro-étale cohomology. Continue reading

An exceptional review of Tensor Categories

I have fallen behind in my posts about exceptional reviews in MathSciNet.  Let’s try to catch up with an excellent review of the book Tensor Categories by Pavel Etingof, Shlomo Gelaki, Dmitri Nikshych, and Victor Ostrik.  The review is written by Julien Bichon, who has written (so far) over 60 reviews.  There are several very good aspects of Bichon’s review.  One can immediately see that it is thorough.  Beyond that, Bichon has organized the review nicely, telling the reader first what the book is about (and also what it is not about) and why it might be interesting.  He also explains what the expectations on the reader are.  Bichon then provides a chapter-by-chapter discussion of the contents, calling out the highlights and pointing out where helpful examples occur.  The review finishes with a summary and a recommendation.
