Throughout this chapter all spaces dealt with are assumed to be locally compact Hausdorff spaces. The base ring L will be taken to be a principal ideal domain, and all sheaves are assumed to be sheaves of L-modules. Note that over a principal ideal domain (and, more generally, over a Dedekind domain) a module is injective if and only if it is divisible.
