Brauer-Manin obstructions for sections of the fundamental group

Stix, J (Heidelberg)
Thursday 27 August 2009, 11:00-12:00

Seminar Room 1, Newton Institute


We introduce the notion of a Brauer-Manin obstruction for sections of the fundamental group extension of varieties over number fields. This obstruction is then shown in an example to yield a proof for the absence of sections.
