Abstract: We define and compare the Zariski, étale and Nisnevich topologies. We explain how the Nisnevich topology incorporates useful features of the Zariski and étale topologies. We prove that, for the Nisnevich topology, it suffices to check the sheaf condition on 'distinguished squares'. Then we define fibres of sheaves in the Nisnevich topology.
