Generalized Operation and the Categorical Equivalence of the Abbott Algebras and Quantum Logics

Considering the inference rules in generalized logics, J.C. Abbott arrives to the notion of orthoimplication algebra (see Abbott (1970) and Abbott (Stud. Logica. 2:173-177, XXXV)). We show that when one enriches the Abbott orthoimplication algebra with a falsity symbol and a natural $$-type operation, one obtains an orthomodular difference lattice as an enriched quantum logic (see Matoušek (Algebra Univers. 60:185-215, 2009)). Moreover, we find that these two structures endowed with the natural morphisms are categorically equivalent. We also show how one can introduce the notion of a state in the Abbott $$ algebras strenghtening thus the relevance of these algebras to quantum theories.
