| Title: | Incompleteness and undecidability |
| Seminar: | Logic Seminar |
| Speaker: | Stephen G. Simpson, Pennsylvania State University |
| Abstract: |
| Let Q be Robinson's weak theory of arithmetic. We use recursion-theoretical methods to show that Q is essentially undecidable. Consequently, any recursively axiomatizable theory in which Q is interpretable is undecidable and incomplete. This is a strong version of Goedel's First Incompleteness Theorem. |
