- Image_functors_for_sheaves abstract "In mathematics, especially in sheaf theory, a domain applied in areas such as topology, logic and algebraic geometry, there are four image functors for sheaves which belong together in various senses.Given a continuous mapping f: X → Y of topological spaces, and the category Sh(–) of sheaves of abelian groups on a topological space. The functors in question are direct image f∗ : Sh(X) → Sh(Y) inverse image f∗ : Sh(Y) → Sh(X) direct image with compact support f! : Sh(X) → Sh(Y) exceptional inverse image Rf! : D(Sh(Y)) → D(Sh(X)).The exclamation mark is often pronounced "shriek" (slang for exclamation mark), and the maps called "f shriek" or "f lower shriek" and "f upper shriek" – see also shriek map.The exceptional inverse image is in general defined on the level of derived categories only. Similar considerations apply to étale sheaves on schemes.".
