The structure of the lattices of quasivarieties

Algebra Universalis, 1994
For an algebraic system \(A\) and a quasivariety \(\mathcal K\) let \(\text{Con}_{{\mathcal K}} A\) be the lattice of all congruence relations \(\theta\) on \(A\) such that \(A/\theta\in {\mathcal K}\). Define the embedding relation \(\leq\) as follows: \(\theta\leq \theta'\) iff \(A/\theta'\) is embeddable into \(A/\theta\).
