DeMorgan quasirings

Correspondence between Boolean Algebras and Boolean rings is generalized for DeMorgan algebras and so-called DeMorgan quasirings such that the subalgebra of complemented elements of a DeMorgan algebra form...

Constructivizability of the Boolean algebra B(?) with a distinguished automorphism

A constructivizability criterion for the Boolean algebra B(?) with a distinguished automorphism is given. As a consequence of the criterion, combined with a result due to I. Sh. Kalimullin, B. M. Khoussainov, and A. G. Melnikov, we ...

Representation of States on MV-algebras by Probabilities on R-generated Boolean Algebras

Any MV-algebra M can be embedded as a lattice in the Boolean algebra B(M) that is R-generated by M. We relate the study of states on an MV-algebra M to the study of finitely additive probabilities on B(M)....

Orthoalgebras as pastings of Boolean algebras

We correct a mistake in the description of orthoalgebras as pastings of Boolean algebras. We present a corrected structural theorem.

A common generalization of ortholattices and boolean quasirings

In (2) a common generalization of Boolean algebras and Boolean rings was introduced. In similar way we introduce a common generalization of ortholattices and Boolean quasirings....

Operators on GMV-algebras

Closure GMV-algebras are introduced as a commutative generalization of closure MV-algebras, which were studied as a natural generalization of topological Boolean algebras....

Boolean and central elements and Cantor-Bernstein theorem in bounded pseudo-BCK-algebras

Boolean and central elements of bounded pseudo-BCK-algebras are studied. Boolean elements form a largest boolean subalgebra and include central elements, which theoremis proved, generalizing similar results for sig...

A characterization of horizontal sums of Boolean rings

Bijective correspondence between Boolean algebras and Boolean rings was generalized for ortholattices. The aim of the paper is to characterize those ring-like structures that correspond to horizontal sums of Boolean

A Cantor-Bernstein theorem for S-complete MV-algebras

The Cantor-Bernstein theorem was extended to S-complete boolean algebras by Sikorski and Tarski. Chang's MV-algebras are a nontrivial generalization of boolean algebras: they stand to the infinite-valued c...
