SUMMARY:Séminaire TNGA : Kazuki Yamada
DESCRIPTION:Le séminaire commencera exceptionnellement à 14h30. \n\n\n\nOrateur : Kazuki Yamada (Gakushuin University) \n\n\n\nTitre : Log rigid fundamental groups \n\n\n\nRésumé : For semistable log schemes over a field of characteristic p\, several cohomology theories can be considered depending on the choice of a base ring and a log structure on it. \n\n\n\nFurthermore\, for each cohomology theory\, a fundamental group is defined as the Tannaka dual of the category of coefficient sheaves\, and each plays a different role. \n\n\n\nAs a result of comparing these fundamental groups\, I would like to talk about the following three theorems: \n\n\n\n1). Homotopy exact sequence with respect to monodromy\, \n\n\n\n2). Homotopy exact sequence with respect to Frobenius\, \n\n\n\n3). Hyodo–Kato isomorphism for fundamental groups.
