Course Summary

Type systems and semantics are mathematical tools for precisely describing aspects of programming language. A type system imposes constraints on programs in order to guarantee their safe execution, whilst a semantics specifies what a program will do when executed. This course gives an introduction to the main ideas and methods of type systems and semantics. This enables a deeper understanding of existing programming languages, as well as the ability to design and specify new language features. The course also introduces relevant parts of logic and discrete mathematics used to describe types and semantics.
