Involutive quantales have been recently introduced by the first author in the course of his search for algebraic invariants of \(C^*\)-algebras. In the present paper, this new structure is related to classical algebraic structures appearing in quantum logic. Notably, it is shown that orthocomplemented lattices correspond to certain involutive quantales. This result is closely connected to the representation of orthocomplemented lattices using Foulis semigroups. These involutive quantales generalize the usual quantales of binary relations.
For the entire collection see [Zbl 0771.00047].
