Conformity and Measuressures are usually regarded as essentially such homomorphic representations. Let us say, as is customary in measurement theory, that the function h on A into B is a . on (or of) the relational structure 〈A,ρ〉 into 〈B,σ〉 iff for all x.,...,x. ∈ A, ..

Transitions Between Systems of Relationalsons as a device for studying dependence, and this will determine the form and content of the chapter. In section 7.1 we generalize the notion of finitary system of relationals from section 3.4 so that a system of relationals may consist of infinitely many relationals, and give a short recapitulation
