Expressing the meaning of programs in mathematics and automatically verifying that they are correct.

AboutAbout the lab
The meaning of programs, in the language of mathematics.
Prof. Tsukada studies programming language theory.
Using tools such as mathematical logic, category theory, and machine learning, the lab treats programs as mathematical objects.
A particular recent interest is game semantics and related models.
Another pillar is automated verification, in which machines check whether programs run correctly.
Key terms
- programming language theory
- A field that studies the mechanisms and meaning of programming languages as mathematics
- game semantics
- An approach that represents the meaning of a program as an interaction in a game in which two players move alternately
- category theory
- A theory that grasps mathematical structures in a unified way by looking only at objects and the arrows between them
