I’m about to write a series of posts on Borger’s notion of geometry over the field with one element using lambda-rings. Problem remains : where should I post them? Here, or elsewhere? In other words, are there any humans left here (or are the 50 to 60 daily hits robot-performed), and, more importantly, are any [...]

Alain Connes and Katia Consani have updated their paper On the notion of geometry over F_un In the revised version, they include a definition for the notion of varieties that are not affine and go a bit further adding a new section with proposals for a new notion of scheme over F_un that involves replacing [...]

Slides are available of a talk given last week in Reims on Manin’s analytic F_un-geometry.

The prep-notes for the halloween-talk on “F_un and other ghost stories” at the Arts are available.

The Fields Institute organizes a Workshop on Arithmetic Geometry with talks by Soule, Consani and Durov a.o. and topics including Arakelov geometry (‘including the infinity-adic’) and ‘Generalized rings and schemes’.

Our highly paid IC-experts do not know that MPG also stand for the Max Planck Gesellschaft and that the string .mpg. is contained in all official email-addresses from MPI … This almost prematurely killed this blog.
