Tóm tắt: In 2006, H. Esnault and P.H. Hai constructed the map between the group cohomology of the Tannaka group scheme H^n(pi(X/K), V) and algebraic de Rham cohomology H^n_dR(X/K, (V,
abla)) via Tannaka duality. They also gave a comparison between these cohomologies for n=0,1. In this talk, we extend this result to all dimensions of the group cohomology of the Tannaka fundamental group of projective smooth curves with genus g ≥ 1 (or abelian varieties over K).
