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

Handwritten notes from the third and fourth lectures at the MPI F_un seminar.

Katia Consani gave a talk “On the notion of geometry over F_un” at the Fields institute.

“One can postulate, of course, that spec(F_un) is the absolute point, but the real problem is to develop non-trivial consequences of this point of view.”

In a follow-up post, F_un and the braid group – a note of skepticism, arguments are collected **against** the claim that the d-string braid group should be invertible dxd matrices over the polynomials over F_un.

Don’t be fooled by introductory remarks to the effect that ‘the field with one element was conceived by Jacques Tits…’ Let’s have it out into the open : F_un mathematics’ goal is no less than proving the Riemann Hypothesis.

Grothendieck’s anabelian geometry is an example of noncommutative F_un geometry. Javier starts this series with ramblings on how the folklore about F_un can be used to relate linear and permutation representations of finite groups.

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.
