WebbNotes to. Recursive Functions. 1. Grassmann and Peirce both employed the old convention of regarding 1 as the first natural number. They thus formulated the base cases differently in their original definitions—e.g., By x+y x + y is meant, in case x = 1 x = 1, the number next greater than y y; and in other cases, the number next greater than x ... WebbReducibility I We show a problem decidable/undecidable by reducing it to another problem. One type of reduction: mapping reduction. De nition I Let A, B be languages over . A is mapping reducible to B, written A m B, if there is a computable function f : ! such that w 2A if and only if f (w) 2B. I Function f is called the reduction of A to B ...

WebbMapping Reducibility If there is a mapping reduction from language A to language B, we say that language A is mapping reducible to language B. Notation: A ≤ M B iff language A is mapping reducible to language B. Note that we reduce languages, not machines. Interesting exercise: Show ≤ M is reflexive and transitive, but not antisymmetric.

The axiom of reducibility states that any truth function (i.e. propositional function) can be expressed by a formally equivalent predicative truth function.

The direct sum of two representations (ˆ 1;V 1) and (ˆ 2;V 2) is expressed as (ˆ 1 ˆ 2;V 1 V 2), where ˆ 1 ˆ 2 has block diagonal action on V 1 V 2. The following theorem allows us to establish the Complete Reducibility Theorem, one of the major theorems of representation theory.
