Res cor (ii) shq (K) −→ shq (L)G −→ shq (K) is exact. Proof. A nontrivial calculation with symbols, for more details see ([ BK, Prop. 4 ]. Lemma 2. Let K and L be as above. The following conditions are equivalent: res cor (i) hq−1 (K) −→ hq−1 (L)G −→ hq−1 (K) is exact. ∪b res (ii) hq−1 (K) −→ hq (K) −→ hq (L) is exact. Geometry & Topology Monographs, Volume 3 (2000) – Invitation to higher local fields Part I. Section 4. Cohomological symbol for henselian discrete valuation field 49 Proof. This is a property of the cup product of Galois cohomologies for L/K .
