WebUtilising space subdivision the duality concept can be performed under different conditions (topography, ownership, sensors coverage) and organised in a Multilayered Space-Event Model (Becker et ... A form of Poincaré duality was first stated, without proof, by Henri Poincaré in 1893. It was stated in terms of Betti numbers: The kth and ()th Betti numbers of a closed (i.e., compact and without boundary) orientable n-manifold are equal. The cohomology concept was at that time about 40 years from being clarified. In his 1895 paper Analysis Situs, Poincaré tried to prove the theorem using topological intersection theory, which he had invented.
