Two new blogs: DZB and Chromotopy

Posted by Andreas Holmstrom on April 1, 2013

Just wanted to recommend two blogs that I discovered quite recently. One is DZB’s blog, where I learnt about the really cool Database of L-functions, modular forms, and related objects. The other one is Chromotopy, where I particularly enjoy the posts of Eric Peterson. A few sample posts from Eric: Iwasawa theory for chromatic localizations, a series of posts on the Devinatz-Hopkins-Smith paper, and Bundles for adults.

Polymath in a TED talk

Posted by Andreas Holmstrom on November 22, 2011

Michael Nielsen’s TED talk Open Science Now! from earlier this year was recently posted on the TED site. For people already interested in these things it doesn’t contain any surprises, but the ideas are certainly worth spreading, and the Polymath project features as the opening story :-)

Book draft by Jardine on local homotopy theory

Posted by Andreas Holmstrom on September 15, 2011

Rick Jardine recently posted a draft on his webpage for a book on local homotopy theory. He writes: “This a partial, rough manuscript for a monograph, which is tentatively to be published by Springer-Verlag. The book is meant to be a basic account of the homotopy theories of simplicial sheaves and presheaves, and the stable homotopy theory of presheaves of spectra. Selected applications are included.” The pdf file is available here.

Early Bourbaki seminars now freely available

Posted by Andreas Holmstrom on June 11, 2011

Until quite recently, the first 10 volumes of the Bourbaki seminars were under subscriber-access only at NUMDAM, but now they are freely available! These 10 volumes cover the years 1948-1968 and hence contain many gems from the early days of scheme theory and the development of cohomological tools in algebraic geometry.

Handbook of K-theory available online!

Posted by Andreas Holmstrom on November 24, 2010

Great news – the wonderful handbook of K-theory is now freely available online here. It contains a number of useful and well-written survey articles, including Levine’s survey on mixed motives, Kahn’s survey on conjectures in arithmetic geometry, Gillet’s survey on K-theory and intersection theory, and much much more.

Resources on motivic homotopy theory

Posted by Andreas Holmstrom on December 14, 2008

I found a really nice page today, maintained by Aravind Asok, with notes and resources on motivic homotopy theory. Worth checking out.
