The weak hereditary class of a variety

Wiktor Bartol, Francesc Rosselló (2006)

Czechoslovak Mathematical Journal

Similarity:

We study the weak hereditary class $S_{w} (𝒦)$ of all weak subalgebras of algebras in a total variety $𝒦$ . We establish an algebraic characterization, in the sense of Birkhoff’s HSP theorem, and a syntactical characterization of these classes. We also consider the problem of when such a weak hereditary class is weak equational.
