Webbis called a \partial recursive" function if it is computed by some Turing Machine M j, i.e. whenever f(x) =y, if y∈N we have M j(x) ↓=yand if y=⊥we have M j(x) ↑. Every Turing Machine computes some partial recursive function, and we write ’ j to denote the partial recursive function computed by M j. A \total recursive" function is a ...

WebbRecursion Theory in Set Theory Theodore A. Slaman 1. Introduction Our goal is to convince the reader that recursion theoretic knowledge and ex- perience can be successfully applied to questions which are typically viewed as set theoretic. Of course, we are not the first to make this point. Webbunderstanding entails three things: knowledge of the math-ematical construct and related theory, knowing the class of situations to which this theory can be applied, and a referential mapping between the theory and the situations. He does not however, suggest how this mapping is devel-oped or grows. He infers but does not give a process model.

We propose a general theory for constructing functorial assignments for a large class of functors from a certain category of bordered surfaces to a suitable target category of topological vector spaces. The construction proceeds by successive excisions of … WebbA structurally recursive function uses the same idea to define a recursive function: "base cases" handle each minimal structure and a rule for recursion. Structural recursion is usually proved correct by structural induction; in particularly easy cases, the inductive step is often left out.
