Systems of difference equations on a vector valued function that admit 3D space of scalar potentials
For known involutive maps on CP1 times CP1, the paper exhaustively lists the 3D space of separated-variable invariants and uses them to derive vertex potentials, recovering the ABS list of integrable difference equations.
