undecidability results in mathematics
shows every recursively enumerable set can be represented as the set of parameter values for which a polynomial equation with integer coefficients has a solution in the remaining variables
no algorithm can decide solvability of arbitrary polynomial equations with integer coefficients in several variables
recursively enumerable subsets of the natural numbers coincide with Diophantine subsets
there exist specific polynomial equations whose solvability encodes arbitrary computations
states every recursively enumerable set of natural numbers is Diophantine
typicalFormulation for every recursively enumerable set S subset of N there exists a polynomial p with integer coefficients such that n is in S iff there exist integers x1,...,xk with p(n,x1,...,xk)=0
