Hi! I am Antonin Callard and I am a PhD student on symbolic dynamics and its connections to computability in Caen (France) under Pascal Vanier. If you want to learn more about me (or get my email address), you can visit this page. If you want to read my personal blog, you can go here. In any case, welcome!
✨ Since I am in the last year of my PhD, I am currently looking for postdoc positions beginning in September 2025: if you know of someone who knows of someone who maybe has the money to fund such positions in symbolic dynamics, computability, or information theory/complexity, I am definitely interested!
Agenda
Current and upcoming activities
While I mostly spend my time writing my thesis these days, I will be in Amiens for Diadisc 7 from December 8th to December 11th. This seems like a very interesting attempt to make a low-carbon international conference: it will be held in three countries simultaneously with both in-person talks and half-day joint videoconferencing sessions. If you were to head there and want to chat, I would be very glad to!
Recent activities
On the science side of things, I have recently been working with Léo Paviet Salomon and Pascal Vanier on extender sets of multidimensional subshifts. In particular, we computationally characterized the possible values of extender entropies (i.e. the asymptotic growth of the extender set sequence) of sofic and effective $\Z^d$ subshifts. A draft is available on arXiv, and comments are much welcome!
