The objective of this course is to present the three sides of the Curry-Howard-Lambek correspondence between proofs, programs and denotational semantics, with an emphasis on the proof-theoretical insights provided by Linear Logic.

- Olivier Laurent (Thursday 1:30pm - 3:30pm)
- Colin Riba (Wednesday 8:00am - 10:00am)

- The course will be partly physical and partly remote.
- The physical part is in room B1.
- The remote part will use BBB.
- Groups for physical vs. remote are on the pad.
- Connection informations for remote attendance are on the pad.

- Programs part (Wednesday, Colin Riba)
- Proofs part (Thursday, Olivier Laurent)

- Proofs
- Sequent calculus for classical and intuitionistic logics
- Classical and intuitionistic linear logic
- Proof nets
- Symmetric monoidal closed categories
- The relational model

- Programs
- Gödel's System T
