SUMMARY

The discussion centers on proving that a recursively enumerable theory T is axiomatizable, meaning there exists a recursive set P such that the Theory of P equals T. Participants highlight the use of compactness to demonstrate the converse of the statement but express uncertainty regarding the direct proof of the original claim. The conversation emphasizes the need for a structured approach to establish the axiomatizability of T.

PREREQUISITES
  • Understanding of recursively enumerable sets
  • Familiarity with axiomatizable theories
  • Knowledge of compactness in logic
  • Basic concepts of formal proofs and set theory
NEXT STEPS
  • Study the properties of recursively enumerable sets in detail
  • Explore the concept of axiomatizability in formal logic
  • Research compactness theorem applications in model theory
  • Learn about recursive sets and their implications in logic
USEFUL FOR

Logicians, mathematicians, and students of formal logic who are interested in the foundations of axiomatic systems and the properties of recursively enumerable theories.

Homework Statement



Suppose T is recursively enumerable. Show that T is actually axiomatizable (there is a recursive set P such that Theory of P = T).


The Attempt at a Solution



The converse of the question is easy to show, by using compactness. But I have no idea how to do this one.
