Course Description

This course is an introduction to the theory of programming languages. It develops the mathematical tools for specifying and reasoning about the static and dynamic semantics of programming languages. The course covers various different techniques for specifying language semantics.

Lectures

Because this is the first offering of this class, the exact syllabus is undecided. We do expect to cover most (if not all) of the following topics:

  • Review of Mathematical Tools: logic, sets, relations, lattices, term algebras, induction, etc.

  • The λ-calculus; axiomatic and operational semantics

  • The Church-Rosser Theorem

  • PCF (Programming Computable Functions)

  • Large-step operational semantics

  • Small-step operational semantics

  • Abstract machines

  • The simply-typed λ-calculus (STLC)

  • Simple types for PCF

  • Relating static and dynamic semantics (soundness)

  • Hindley-Milner Polymorphism

  • Mutable state

  • Non-local control flow (e.g., exceptions)

  • Abstract interpretation

  • Logical relations

Textbook

The textbook for the course is

Introduction to the Theory of Programming Languages, by Gilles Dowek and Jean-Jacques Lévy. Springer-Verlag, 2011.

The book is available online via the University Library.

Coursework

The course work consists of attending (and participating in) the course lectures; six or seven written homework assignments, and two exams. There are no programming assignments for this class.

CMSC 32450

This course also has a graduate-version. Students who are enrolled in the graduate class will be expected to do some additional work beyond that required for 22450.

Exams

There will be two exams in this class. The first will be an in-class exam on Tuesday, April 29. The second will be during exam week on Thursday, May 29 from 12:30-2:30 PM in JCL 011.

Academic Honesty

Note

The following discussion is owed to Stuart Kurtz

The University of Chicago is a scholarly academic community. You need to both understand and internalize the ethics of our community. A good place to start is with the Cadet’s Honor Code of the US Military Academy: "A Cadet will not lie, cheat, or steal, or tolerate those who do." It is important to understand that the notion of property that matters most to academics is ideas, and that to pass someone else’s ideas off as your own is to lie, cheat, and steal.

The University has a formal policy on Academic Honesty, which is somewhat more verbose than West Point’s. Even so, you should read and understand it.

We believe that student interactions are an important and useful means to mastery of the material. We recommend that you discuss the material in this class with other students, and that includes the homework assignments. So what is the boundary between acceptable collaboration and academic misconduct? First, while it is acceptable to discuss homework, it is not acceptable to turn in someone else’s work as your own. When the time comes to write down your answer, you should write it down yourself from your own memory. Moreover, you should cite any material discussions, or written sources, e.g.,

Note: I discussed this exercise with Jane Smith.

The University’s policy, for its relative length, says less than it should regarding the culpability of those who know of misconduct by others, but do not report it. An all too common case has been where one student has decided to "help" another student by giving them a copy of their assignment, only to have that other student copy it and turn it in. In such cases, we view both students as culpable and pursue disciplinary sanctions against both.

For the student collaborations, it can be a slippery slope that leads from sanctioned collaboration to outright misconduct. But for all the slipperyness, there is a clear line: present only your ideas as yours and attribute all others.

If you have any questions about what is or is not proper academic conduct, please ask your instructors.
