The geometry of perpendicularity: the axiomatic multidimensional space and De Morgan’s laws. (Russian. English summary) Zbl 1432.51002

Summary: We propose the short axiomatic for finite dimensional geometrical structure, using only perpendicularity relation. This structure appear projective space in which hold De Morgan’s laws. We show the connection work with the Veblen’s axiom and with partition four elements to pairs various modes. The research is connected with ortholattice, matroids, Galois connections and quantum logic.
