dc.description.abstractEnLet X be a regular scheme, flat and proper over the ring of integers of a p-adic field, with generic fiber X and special fiber X_s. We study the left kernel Br(X) of the Brauer-Manin pairing Br(X)×CH 0 (X) → Q/Z. Our main result is that the kernel of the reduction map Br(X) → Br(X_s) is the direct sum of (Q/Z[1/p])^s⊕(Q/Z)^t and a finite p-group, where s+t=ρ_{X_s}−ρ_X−I+1, for ρ_{X_s} and ρ_X the Picard numbers of X_s and X, and I the number of irreducible components of X_s. Moreover, we show that t>0 implies s>0.
