WebThroughout 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. WebIn mathematics, Borel−Moore homology or homology with closed support is a homology theory for locally compact spaces, introduced by Template:Harvs.. For compact spaces, the Borel−Moore homology coincide with the usual singular homology, but for non-compact spaces, it usually gives homology groups with better properties.. Note: There is an …

Webclass of W in Borel-Moore homology of X, which is by deﬁnition the homology of the complex of locally ﬁnite singular chains. The functoriality of these chains for a proper map f : X !Y is evident, since if C ˆY is compact, f 1C is also, and hence only ﬁnitely many (singular) simplices have image in Y intersecting C. Webcalisation for Borel-Moore etale motivic homology and for Borel-Moore etale homology. 2 1.16. Corollary. Proposition 1.6 holds after replacing L(n) and Z(n) respectively by L(n)[1=p] and Z(n)[1=p], where p is the exponential characteristic of k. Proof. It is enough to check this after tensoring with Q and with Z=l for all l 6= p.

WebSo Borel--Moore homology is the "homology analogue" of compactly supported cohomology. (But the support conditions are reversed, since homology is dual to cohomology.) One can often interpret Borel--Moore homology as relative homology.
