C. Piron, JAUCH-PIRON ORTHOMODULAR POSETS AND PROPOSITIONAL SYSTEMS - A COMPARISON, International journal of theoretical physics, 32(10), 1993, pp. 1981-1984
We compare the structures obtained via orthomodular posets and via pro
positional systems, discussing some examples of the links between them
. Despite some analogies, the two structures are fundamentally differe
