Alexander-Spanier Cohomology
A fundamental result of de Rham Cohomology is that the 
th de Rham Cohomology Vector Space ofa Manifold 
is canonically isomorphic to the Alexander-Spanier cohomology Vector Space 
(also called cohomology with compact support). In the case that is Compact,Alexander-Spanier cohomology is exactly ``singular'' Cohomology.
