PROGRAMMING LANGUAGE THEORY | EDA145 |

**Aim**

The course will give a qualified perspective on the semantics of programming languages and ability to read and understand scientific papers in a wider field than the course contents.

*Knowledge and understanding*

For a passing grade the student must

- be able to understand the semantics of program constructs given as formal operational, axiomatic, and denotational semantics.
- be able to understand execution models for functional and logic programming languages.

*Skills and abilities*

For a passing grade the student must

- be able to specify formal semantics given as informal descriptions.
- be able to interpret recursive definitions using least fixed points.
- be able to make computations using lambda calculus and combinatory logic.
- be able to construct programs for type deduction and unification.
- be able to prove program properties such as correctness and equivalence.

*Judgement and approach*

For a passing grade the student must

- be able to value program constructs based on their formal semantic descriptions.

**Contents**

Syntax of programming languages and abstract representation of programs. Operational, axiomatic, and denotational semantics. Proofs of program properties.
