Zusammenfassung

We show a conditional exactness statement for the Nisnevich Gersten complex associated to an A(1)-invariant cohomology theory with Nisnevich descent for smooth schemes over a Dedekind ring with only infinite residue fields. As an application we derive a Nisnevich analogue of the Bloch-Ogus theorem for & eacute;tale cohomology over a henselian discrete valuation ring with infinite residue field.
