“…If M is a commutative, finite and flat Kgroup scheme, let H i (G K , M) (respectively, H i (G v , M)) denote the Galois cohomology group H i (G K , M(K s )) (respectively, H i (G v , M(K s v ))). The validity of the Hasse principle for M(K s ), i.e., the injectivity of the canonical localization map H 1 (G K , M) → all v H 1 (G v , M) in Galois cohomology, has been discussed in [12,6].
