### Topological representation of sheaf cohomology of sites, by Carsten Butz and Ieke Moerdijk

	 *	   *	   *
H (S,A) = H (X ,phi A)
S

for any abelian sheaf A on S. As a particular case, this will give for any scheme Y a topological space X_(Y) and a functorial isomorphism between the \'etale cohomology H*(Y_{et},A) and the ordinary sheaf cohomology H^*(X_(Y),\varphi^*A), for any sheaf A for the \'etale topology on Y.
