Abstract.

Let X be an algebraic variety defined over a number field. We compare miscellaneous (abelian and non-abelian) cohomological obstructions to the Hasse principle and weak approximation for X to the Manin obstruction.

Résumé.

Soit X une variété algébrique définie sur un corps de nombres. Nous comparons diverses obstructions cohomologiques (abéliennes et non-abéliennes) au principe de Hasse et à l'approximation faible sur Xà l'obstruction de Manin.
