Poe, in The domain of Arnheim.

Here is a description of my past research and research project and a short CV (updated 31st of Oct. 2020), and here a description of some teaching principles I believe in. One can find a history of my writting on page "Research documents", and information and archives on the work group "Exact computation of topological entropy of multidimensional subshifts of finite type" on page "Work group", and a commented bibliography related to my current and past research on page "Bibliography".
