In this note we first extend Theorem 4.2 from Xiang-Yun (Semigroup Forum 61:159–178, 2000) by showing that the set of all regular congruences with the ordering $$\subseteq $$ is actually an algebraic lattice. Afterwards, we derive Maltsev type desc

In an attempt to describe the partially ordered monoid of operators generated by the operators H (homomorphic images), S (subalgebras), $${P_{\rm f}}$$ (filtered products) for the variety $${\mathcal{R}_{\rm c}}$$ of commutative rings, several result

We prove that epimorphisms are surjective in certain categories of ordered $$\mathcal {F}$$-algebras. It then turns out that epimorphisms are also surjective in the category of all (unordered) algebras of type $$\mathcal {F}$$.

A class K of T -coalgebras is called a covariety if K =SHΣ( K ) . SHΣ is just one of several class operators which can be formed by composing H, S and Σ . In this paper, we show that starting from H, S and Σ one can form exactly 13 different clas
