WebApr 14, 2024 · Various types of such quasirings were described and compared by the authors in “A note on orthopseudorings and Boolean quasirings”. A similar way was applied when ring-like structures were assigned to De Morgan algebras in Chajda I, Eigenthaler G. (2008). The resulting ring-like structures were called De Morgan quasirings. WebFirst, the algebra need not have a unit for the multiplication. If it does have a unit, we write it as 1 or 1 Aand say that Ais unital. Secondly, the multiplication is not necessarily commutative. That is, it is not generally the case that ab= ba, for all a;b.
