The next BelgianDutch Algebraic Geometry seminar will be combined with the Grothendieck Seminar. This will take place on Friday, March 23, 2018 in Leiden. The speakers are José Burgos, Florian Ivorra and Peter Jossen.
This meeting is sponsored by the Diamant Cluster 
Venue: Leiden University, Havingazaal, LMUY building. Use the entrance of the Oort building (Niels Bohrweg 2, 2333 CA Leiden), take the stairs to the walkway on the first floor to the LMUY building, at the end turn left and then immediately right, the room is at the end on your right. Coordinates of the lecture room: 52.168315, 4.460591.
A dinner will be organised, starting at 18:30. If you want to participate in this dinner then sign up for it by sending an email to Bas Edixhoven, edix@math.leidenuniv.nl, and include your dietary wishes if necessary, no later than Wednesday March 14.

13:3014:30  Florian Ivorra (FRIAS, Freiburg)  Quasiunipotent motives
Abstract: Quasiunipotent motives were introduced by J. Ayoub who
related them to motives of rigid analytic varieties. In this talk, I
will give an overview of their properties focusing on their relations
with nearby cycles functors and monodromy action.

15:0016:00  Peter Jossen (ETH Zürich)  Galois groups and Motivic Fundamental groups
Abstract: Let k a subfield of the complex numbers. I will explain what
is known and what is still conjectured about the relation between the
absolute Galois group of k and various motivic fundamental groups of
k. The motivic fundamental groups are: the one obtained from Nori's
tannakian category of mixed motives, the one obtained from Ayoub's
weak tannakian formalism, and André's fundamental group for motives
with respect to motivated cycles.

16:3017:30  José Burgos Gil (ICMAT, Madrid)  Grothendieck's period conjecture and zeta values
Abstract: In this survey talk we will give an overview of
Grothendieck's period conjecture and explain how this conjecture
implies that the values of the Riemann zeta function at odd integers
bigger that 3 are algebraically independent.
