PhD student | Institut Polytechnique de Paris & Inria Saclay
Hi! I am Jui-Hsuan Wu, a PhD student at LIX, Ecole Polytechnique & Inria Saclay advised by Dale Miller. I also go by the name Ray.
Before, I studied computer science and mathematics at Ecole Normale Supérieure and got a master degree from Master Parisien de Recherche en Informatique. You can have a look at my CV (Version française).
I am working on term representations based on proof theory.
Terms (or expressions) are essential in many different settings: mathematical proofs, programming languages, proof assistants and so on. Proof theory has been widely used to motivate the design of term structures.
The goal of my PhD project is to build a logical framework based on proof theory to describe/unify/justify different term representations, in the hope that proof-theoretic considerations will on one hand provide careful and formal descriptions of term structures and on the other hand give us more insights on terms.
Instead of using proof systems such as Gentzen’s natural deduction and sequent calculus, we use the focused proof system LJF in order to give more structure to proofs. The notion of polarization gives the flexibility to construct differents forms of proofs, which is a desirable feature since we want to describe different term structures in our system.
I am also working on graphical representations for terms related to the term structures obtained as described above.
Some problems I am thinking about:
How can terms (proofs) built using different polarization interact with each other?
How can terms (proofs) built using different axioms interact with each other?
What is the “meaning” of a term from a purely logical point of view?
I am from New Taipei, Taiwan.
