Meaningless statements
Increasingly, discrete mathematics is influenced by connections with other fields. We give one example of a broad topic in the field of discrete mathematics that comes from the social sciences, and in particular from the theory of measurement that has been developed to put measurement, especially in the social sciences, on a firm mathematical foundation. The key concept is that of meaningful st...
متن کاملMeaningless Terms in Rewriting
We present an axiomatic approach to the concept of meaninglessness in finite and transfinite term rewriting and lambda calculus. We justify our axioms in several ways. They can be intuitively justified from the viewpoint of rewriting as computation. They are shown to imply important properties of meaninglessness: genericity of the class of meaningless terms, confluence modulo equality of meanin...
متن کاملMeaningless terms in
We present an axiomatic approach to meaninglessness in nite and transsnite term rewriting and lambda calculus. We justify our axioms in two ways. First, they are shown to imply important properties of mean-inglessness: genericity of the class of meaningless terms, the consistency of equating all meaningless terms, and the construction of BB ohm trees. Second we show that they can be easily veri...

متن کاملOn Undefined and Meaningless in Lambda Definability
We distinguish between undefined terms as used in lambda definability of partial recursive functions and meaningless terms as used in infinite lambda calculus for the infinitary terms models that generalise the Böhm model. While there are uncountable many known sets of meaningless terms, there are four known sets of undefined terms. Two of these four are sets of meaningless terms. In this paper...
