    • Characterizing asymptotic randomization in abelian cellular automata 
      Hellouin de Menibus, Benjamín; Salo, Ville; Theyssier, G. (Cambridge University Press, 2020)
      Abelian cellular automata (CAs) are CAs which are group endomorphisms of the full group shift when endowing the alphabet with an abelian group structure. A CA randomizes an initial probability measure if its iterated images ...
    • Necessary conditions for tiling finitely generated amenable groups 
      Hellouin de Menibus, Benjamin; Maturana Cornejo, Hugo (American Institute of Mathematical Sciences, 2020)
      We consider a set of necessary conditions which are efficient heuristics for deciding when a set of Wang tiles cannot tile a group. Piantadosi [19] gave a necessary and sufficient condition for the existence of a valid ...
