On the duality theorems for the Betti numbers of topological manifolds. SS. 530-533. In: Proceedings of the National Academy of Sciences. Vol. 16, No. 8.
Washington, 1930. - (25,5 x 17,5 cm). SS. (527)-554. Mit Abbildungen. Original-Broschur.
Erste Ausgabe. - "A by-product of Lefschetz' work on fixed points was his duality theorem, which provided a bridge between the classical duality theorem of Poincaré and of Alexander. The Lefschetz duality theorem states that the p-dimensional Betti number of an orientable n-dimensional manifold M with regular boundary L equals the (n-p)-dimensional Betti number of M modulo L" (DSB). - Gut erhalten. - DSB 18, 534
