Types for Programs and ProofsDAT140/DIT232, study period 1, 2013NewsThe take home exam is now corrected. Unfortunately, we have not been able to do the official reporting of the course because of illness at the student administration office.AimThe development of powerful type systems is one of the most dynamic aspects of modern programming language design. The aim of this course is to provide a solid and broad foundation in type systems for programming languages. The student will be exposed to applications of type-based technology in computer science and learn to use an interactive programming and proof system using dependent types.LiteratureTypes and Programming Languages by Benjamin Pierce, MIT Press.
