Homology of tangent groups considered as discrete groups and scissors congruence Original Research Article

Extensions of results of Sah (1986, 1989) and Bökstedt et al., joined with previous results of the author, give a new approach to a homological result1 known, by Dupont, to be equivalent to the Sydlerʹs theorem on scissors congruences of polyhedras in Euclidean three-space.
