syllabus

This course is an introduction to modern approaches to the semantics of programming languages. The course will introduce denotational, axiomatic, and operational approaches to defining the semantics of simple programming languages. It will also introduce the mathematical techniques necessary for using these approaches, including the study of domains and continuous functions and of proof systems and logics. Finally, we will discuss the λ-calculus, a simple model of computation that underlies modern functional programming languages, and its connections to logic and proof theory.

The syllabus is available here. The syllabus spells out the details of grading, expectations, and so forth.

announcements

11/12 Homework 6 is released. This is the final homework of the semester. It will be worth 1.5x the other homework assignments in determining your homework grade.
9/5 The due date for homework 2 has been extended to September 10.
8/24 The due date for homework 1 has been extended to September 4. This does not mean the next homework will be delayed; it will still be assigned on August 27
8/20 Welcome to EECS 762! Homework 1, including TeX sources, is posted.
