Abstract: We examine Verdier duality for locally compact spaces of finite cohomological dimension.We give some explicit examples of the dualizing sheaf. We show that this duality is is exact and preserves quasi-isomorphism and that a complex of sheaves is naturally identified with its double dual.
After this discussion we will begin to construct stratified spaces with complexes of sheaves isomorphic to their Verdier duals.
