JI-distributive, dually quasi-De Morgan semi-Heyting and Heyting algebras
Hanamantagouda P. Sankappanavar
The variety DQD of semi-Heyting algebras with a weak negation, called dually quasi-De Morgan operation, and several of its subvarieties were investigated in a series of four papers…
Order in Implication Zroupoids
Juan M. Cornejo, Hanamantagouda P. Sankappanavar
The variety of implication zroupoids was defined and investigated by Sankappanavar ([7]) as a generalization of De Morgan algebras. Also, in [7], several new subvariet…
Semisimple Varieties of Implication Zroupoids
Juan M. Cornejo, Hanamantagouda P. Sankappanavar
It is a well known fact that Boolean algebras can be defined using only implication and a constant. In 2012, this result was extended to De Morgan algebras in [8] which led Sankapp…
On Implicator Groupoids
Juan M. Cornejo, Hanamantagouda P. Sankappanavar
In a paper published in 2012, the second author extended the well-known fact that Boolean algebras can be defined using only implication and a constant, to De Morgan algebras-this…
