Amalgamation Property in the subvarieties of Gautama and Almost Gautama algebras
Juan M. Cornejo, Hanamantagouda P. Sankappanavar
Gautama algebras were introduced recently, as a common generalization of regular double Stone algebras and regular Kleene Stone algebras. Even more recently, Gautama algebras were…
Semidistributivity and Whitman Property in Implication Zroupoids
Juan M. Cornejo, Hanamantagouda P. Sankappanavar
In 2012, the second author introduced and studied the variety of implication zroupoids that generalize De Morgan algebras and -semilattices with . An algebra…
Implication Zroupoids and Birkhoff Systems
Juan M. Cornejo, Hanamantagouda P. Sankappanavar
An algebra , where is binary and is a constant, is called an implication zroupoid (I-zroupoid, for short) if A satisfies the identities: $(…
Varieties of Regular Pseudocomplemented de Morgan Algebras
M. E. Adams, H. P. Sankappanavar, Júlia Vaz de Carvalho
In this paper, we investigate the varieties and of regular pseudocomplemented de Morgan and Kleene algebras of range , respectively. Priestley dualit…
The lattice of varieties of implication semigroups
S. V. Gusev, H. P. Sankappanavar, B. M. Vernikov
In 2012, the second author introduced and examined a new type of algebras as a generalization of De Morgan algebras. These algebras are of type (2,0) with one binary and one nullar…
De Morgan Semi-Heyting and Heyting Algebras
Hanamantagouda P. Sankappanavar
The variety DMSH of semi-Heyting algebras with a De Morgan negation was introduced in [12] and an increasing sequence DMSHn of level n, n being a natural number, of its subvarietie…
