Course Projects
Half of your grade in this class will be determined by a course project, which may be completed in small groups. Projects that relate synergistically with other ongoing research are encouraged.
- Groups:
Teams for group projects will consist of one, two, or three students. - Timeline:
- February 17: 2-page Project proposals are due
- April 28: Final Project due
- Topic:
The only requirement is that the topic of the project be somehow related to linear logic. Here are some ideas to get your creative juices flowing:- Write a survey paper about some aspect of linear logic: its connections to memory management, concurrency, mu calculus, separation logic, ...
- Implement a linear-logic-based type system
- Implement a theorem prover based on linear-logic
- Implement a Coq library to solve finite multiset goals similar to how the existing MSet package works for finite sets.
- Formalize a substructural logic in Coq. Prove cut elimination.
- Pick a categorical model of linear logic and work out lots of concrete examples using that model.
