Hi! I'm Antonin Callard. While I prepare a Master's degree, I am a young researcher on symbolic dynamics, computability and topology.


Future talks, scientific events, etc... Let's meet!

Recent activities

I recently gave at talk "Journées SDA2" (the annual meeting for people who work on dynamical systems and automata in France), whose slides are available here. I also gave a presentation about the domino problem during the third edition of our new department seminar at ENS Paris-Saclay, which is dedicated to deepen the relationship between students and the pedagogical staff. I was glad I could participate in this project!

Current research

I currently study symbolic dynamics. In particular, during the last few months, I have focused on surface entropies of subshifts of finity type. Soon, I will start a new internship during which I will study decidability properties of shifts which are invariant under isometries.
