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


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

Recent activities

I recently graduated from M2 MPRI. Earlier, Pascal Vanier and I published a paper on surface entropies of \(\mathbb{Z}^2\) subshifts. I also completed an internship with Benjamin Hellouin de Menibus about the existence of aperiodic configurations in \(\mathbb{Z}^d\) subshifts (a preprint is available).

Current research

I currently study symbolic dynamics. In particular, I am a visitor at the University of Turku (Finland), where I do an internship about automorphism groups of \(\mathbb{Z}\) subshifts under the kind supervision of Ville Salo.
