DRl-semigroups and -algebras
Dual commutative hyper K-ideals of type 1 in hyper K-algebras of order 3.
In this note we classify the bounded hyper K-algebras of order 3, which have D1 = {1}, D2 = {1,2} and D3 = {0,1} as a dual commutative hyper K-ideal of type 1. In this regard we show that there are such non-isomorphic bounded hyper K-algebras.
Dual spaces of totally ordered rings
Dualität zwischen Kategorien topologischer Räume und Kategorien von K-Verbänden.
Dualities for Stone algebras, double Stone algebras, and relative Stone algebras
Dually residuated -monoids having no non-trivial convex subalgebras
In this note we describe the structure of dually residuated -monoids (-monoids) that have no non-trivial convex subalgebras.
