| Résume | In this talk, we give some application for the method to construct fundamental groupsof Tannakian categories using bar complex ofdifferential graded algebras.First example is bar complex of Deligne DAGassociated to mixed Tate structures on an algebraicvariety. Next example is related to pro-$p$ completionof fundamental group of varieties over $\mathbb F_p$.I want to talk a working progress on Hopf algebrarelated to mixed elliptic motif. |
