lattice of convex sublattices of a lattice; congruence relation; representable congruence relation
Let $L$ be a lattice. In this paper, corresponding to a given congruence relation $\Theta $ of $L$, a congruence relation $\Psi _\Theta $ on $CS(L)$ is defined and it is proved that 1. $CS(L/\Theta )$ is isomorphic to $CS(L)/\Psi _\Theta $; 2. $L/\Theta $ and $CS(L)/\Psi _\Theta $ are in the same equational class; 3. if $\Theta $ is representable in $L$, then so is $\Psi _\Theta $ in $CS(L)$.
