"Motives, Foliations and the Conservativity Conjecture"

Arbeitsgemeinschaft at Humboldt Universität zu Berlin

September 24th - 28th 2018



This Arbeitsgemeinschaft will be devoted to Ayoub's proof of the Conservativity conjecture [see here].

The idea is " learning by doing " – similar to the Deninger-Faltings Arbeitsgemeinschaft at Oberwolfach. Participants have to volunteer for one of the lectures described in the program of the Arbeitsgemeinschaft [see here].

Useful references: Ayoub's Spring 2018 lectures on videos, the corresponding lecture notes, Ayoub's 2015 lectures on foliations and motives, more details on localization and on differential Galois theory.

After the deadline for application the organizers choose the actual speakers to give them enough time to understand the subject and to prepare for their lectures.


Applications for participation should be adressed by email to Bruno Klingler prior to the deadline June 8th 2018.
They should include:
  – full name
  – first choice for a talk: no. X, title
  – second choice for a talk: no. Y, title
  – third choice for a talk: no. Z, title
  – for students and post-docs: CV and publication list

Notice: as in Oberwolfach, accommodation will be covered, but in principle travel will be at the charge of the participants.


All lectures will take place in the main building of the Humboldt University at
