Sets, Models and Recursion Theory

Two levels of courses were provided and the advanced lectures are published here except that Dana Scott’s lectures on Set Theory have been replaced by Carol Karp and R. B. Jensen’s papers. Scott’s lectures are now scheduled to appear in the Proceedings of the A.M.S. Set Theory conference in Los Angeles, 1967. The other papers in this volume were presented at the Logic Colloquium which was recognized as a meeting of the Association for Symbolic Logic.
