Lattice homomorphism

Summary

A lattice homomorphism is a map between two lattices that preserves join and meet. Every lattice homomorphism is monotone, but a monotone map need not preserve joins or meets. Lattice homomorphisms are the morphisms of the category of lattices; their kernels are the lattice congruences, and the bijective ones are the lattice isomorphisms.
