Every Grothendieck topos has a special sheaf called a subobject classifier. Here one explicitly calculates cohomology of a space using the machinery of sheaf cohomology. There is a strong finiteness result on sheaf cohomology. Every sheaf of modules is an abelian sheaf. Her holy symbol is a sheaf of wheat stalks. Many generalizations are possible using the language of sheaf cohomology. For example, let formula 73 be an algebraic variety with structure sheaf formula 74. The first courthouse was housed in the Barley Sheaf Inn. "See also"&colon; analytic function, coherent sheaf and vector bundles. Omer is often rendered "sheaf" in English translations. Let formula 37 denote the category of perverse sheaf on formula 8. The most important finiteness condition for a sheaf is coherence. Let formula 31 be a quasi-coherent sheaf on a scheme . The direct image of a coherent sheaf is often not coherent. The special case of the constant sheaf gives the usual zeta function.
