| Abstract: | We propose a framework in which to study invariants of difference equations with the ultimate goal of establishing the (theoretical) existence of effective invariants. The paper is divided into two parts.Part I began with several examples which illustrated some of the difficulties to be overcome and ended with a discussion of the connection between invariants and decompositions of the phase space.In PartII, which is more topological in nature, we now pursue the theme of invariant decompositions |
