OPTIMAL NATURAL DUALITIES FOR SOME QUASIVARIETIES OF DISTRIBUTIVE DOUBLE $p$-ALGEBRAS
M. J. SARAMAGO
Abstract.
Quasivarieties of distributive double $p$-algebras generated by an ordinal sum $nderline M$ of two Boolean lattices are considered. Globally minimal failsets within $\Bbb S(nderline M^2)$ are completely determined; from them all the optimal dualities for these quasivarieties are obtained.
