On Defining Real Consumption

Theory can and should be used to better define real consumption. Bad definitions could very well be the reason for the low growth in consumption. I base this statement on the observation that since 1982 the deflators of the a priori badly defined components of consumption have been increasing much more rapidly than the better defined components. If the price of the badly defined components had ...

On defining dietary fibre.

Establishing a definition for dietary fibre has historically been a balance between nutrition knowledge and analytical method capabilities. While the most widely accepted physiologically-based definitions have generally been accurate in defining the dietary fibre in foods, scientists and regulators have tended, in practice, to rely on analytical procedures as the definitional basis in fact. As ...

On Defining Functions on Trees1

The continuation of the sequence of articles on trees (see [2], [3], [4], [5]) and on context-free grammars ([13]). We define the set of complete parse trees for a given context-free grammar. Next we define the scheme of induction for the set and the scheme of defining functions by induction on the set. For each symbol of a context-free grammar we define the terminal, the pretraversal, and the ...

On Defining Irreducibility

This means that for all n ≥ 2, there exists no first-order sentence Fn in the language Ln = (+,−,×,=, 0, 1, In) satisfying the following property: for any real algebraic variety V of R, if we interpret the n-ary predicate In by membership to V then R |= Fn if and only if V is irreducible. Our proof will imply that irreducibility remains undefinable even if we add the exponential function to Ln....
