• Constant-length random substitutions and gibbs measures 

      Maldonado Ahumada, César Octavio; Trejo Valencia, Liliana; Ugalde, Edgardo (2018)
      "This work is devoted to the study of processes generated by random substitutions over a finite alphabet. We prove, under mild conditions on the substitutions rule, the existence of a unique process which remains invariant ...
    • Information entropy production of maximum entropy markov chains from spike trains 

      Cofré, Rodrigo; Maldonado Ahumada, César Octavio (MDPI, 2018)
      "The spiking activity of neuronal networks follows laws that are not time-reversal symmetric; the notion of pre-synaptic and post-synaptic neurons, stimulus correlations and noise correlations have a clear time order. ...
