Textbook: Concrete set logic: a proof verifier and its application to the basic theorems of analysis. By Domenico Cantone, Eugenio Omodeo, and J.T. Schwartz (Draft manuscript)

You can E-mail me at jack@nyu.edu. The course text is on-line at http://www.settheory.com/intro.html

There will be no examinations. Grades will be assigned on the basis of a final paper, on a subject related to the course, to be selected in consultation with the instructor. A final project proposal is due in week 8. Finished final projects are due one week after the last class. Students actively interested in Computational Logic, perhaps for a dissertation in this area, may wish to undertake a programming project, to be worked out in consultation with the instructor.
