Title: Coproducts In The Categories Of Kleene And Three-valued Łukasiewicz Algebras
Author: Cignoli R.
Abstract: It is given an explicit description of coproducts in the category of Kleene algebras in terms of the dual topological spaces. As an application, a description of dual spaces of free Kleene algebras is given. It is also shown that the coproduct of a family of three-valued Łukasiewicz algebras in the category of Kleene algebras is the same as the coproduct in the subcategory of three-valued Łukasiewicz algebras. © 1979 Polish Academy of Sciences.
