Summary

Gödel incompleteness theorems and mathematical foundations of computer science

Content

Keywords

Gödel, incompleteness theorems, Peano arithmetic, Robinson arithmetic, decidability, recursively enumarable, arithmetical hierarchy, Turing machine, Turing degrees, jump operator, primitive recursive functions, recursive functions, automata, pushdown automata, regular languages, context-free languages, recursive languages, halting problem, universal Turing machine, Church thesis.

Learning Prerequisites

Recommended courses

Mathematical logic (or equivalent). A good understanding of 1st order logic is required - in particular the relation between syntax and semantics.

Important concepts to start the course

1st order logic: syntax, semantics, proof theory, completeness theorem, compactness theorem, Löwenheim-Skolem theorem.

Learning Outcomes

By the end of the course, the student must be able to:

  • Estimate whether a given theory, function, language is recursive or no
  • Decide the class that a language belongs to (regular, context-free, recursive,...)
  • Elaborate an automaton
  • Design a Turing machine
  • Formalize a proof in Peano arithmetic
  • Sketch the incompleteness theorems
  • Propose a non-standard model
  • Argue why Hilbert program failed
