Course description and aims

This course covers the intersection of programming language theory and mathematical logic.
The key notion is "Curry-Howard correspondence", which shows the direct relationship between computer programs and mathematical proofs.
Topics include syntax and semantics of various logics (classical, intuitionistic, modal, etc.), various proof systems (natural deduction, sequent calculus, etc.) , and lambda calculus.

Student learning outcomes

Students will acquire an insight into the logical foundations of computation.

Keywords

Curry-Howard correspondence, lambda calculus, classical logic, intuitionistic logic, modal logic, natural deduction, sequent calculus, Kripke model

Competencies that will be developed

✔ Specialist skills

Intercultural skills

Communication skills

Critical thinking skills

Practical and/or problem-solving skills

Class flow

The course consists of lectures.
Students will have exercise assignments several times.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
