Algebraic properties of paraorthomodular posets
Ivan Chajda, Davide Fazio, Helmut Länger +2
Paraorthomodular posets are bounded partially ordered set with an antitone involution induced by quantum structures arising from the logico-algebraic approach to quantum mechanics.…

On the structure theory of Łukasiewicz near semirings
Ivan Chajda. Davide Fazio, Antonio Ledda
In a previous article by two of the present authors and S. Bonzio, Łukasiewicz near semirings were introduced and it was proven that basic algebras can be represented (precisely, a…
