Motives Seminar-SS 2013
Meeting time and place:
We meet on Tuesdays, 12 Uhr (c.t.) in WSC-S-U-3.01
Program
This semester we will have a seminar on mixed Tate motives and the motivic fundamental group, concentrating on the three papers:
Deligne, P. Le groupe fondamental de la droite projective moins trois points. Galois groups over Q Math. Sci. Res. Inst. Publ., 16,
Deligne, P.; Goncharov, A. B. Groupes fondamentaux motiviques de Tate mixte. Ann. Sci. École Norm. Sup. (4)
Goncharov, A. B.Galois symmetries of fundamental groupoids and noncommutative geometry. Duke Math. J. 128 (2005), no. 2.
finishing with the paper of Francis Brown
Brown, F. Mixed Tate motives over Z. Ann. of Math. (2) 175 (2012), no. 2, 949–976.
as application.
