Abstract:
We study extensions of states between projection structures of JB algebras and generalized orthomodular posets. It is shown that projection orthoposet of a JB algebra $A$ admits the universal extension property if and only if the Gleason theorem is valid for $A$. As a consequence we get that any positive Stone algebra–valued measure on projection lattice of a quotient of a JBW algebra without type $I_2$ direct summand extends to a positive measure on an arbitrary larger generalized orthomodular lattice.References
