Lattice isomorphism is a relationship between two lattices where there exists a bijective function that preserves the lattice operations of meet and join. This means that for any two elements in the lattices, the image of their meet and join in one lattice corresponds to the meet and join of their images in the other lattice. Understanding lattice isomorphisms is crucial for recognizing when two complete or distributive lattices are essentially the same in structure, despite potentially differing in representation.
congrats on reading the definition of lattice isomorphism. now let's actually learn it.
